How To Solve TeamViewer “Commercial Use Suspected!” Problem

No doubt TeamViewer is one of the best, free remote access and remote desktop sharing software over internet.

(**Quick Update** – Teamviewer is a remote desktop sharing software. You should not use TeamViewer to watch movies/ TV shows ! )

Let’s say your friend is facing some computer issues and she does not know much about computers. It’ll be really difficult for you to guide your friend over phone as mostly she’d not understand what to do and your phone bill would run high as well !for

This is where TeamViewer comes in picture and works best. You can sit at the comfort of your house and help your friend who can possibly be sitting thousands of miles away (Make sure you have direct internet connection as TeamViewer does not work if it’s behind proxy).

TeamViewer is free for personal use, but you’ll have to buy a license if you are using it for commercial purposes. Off late I had a few readers e-mailing a common problem they had with TeamViewer. The common problem was that, even though these visitors were not using TeamViewer for commercial purpose they were getting the following message:

“Commercial Use Suspected”

In such case, my first suggestion is that you contact TeamViewer team and inform them about the problem and see if they can solve the issue.

However, there is a way to solve this, but this should be used only if you don’t get a reply from teamviewer and is a bit of technical process, so you have to dabble your hand in it only if you know what you are upto.

1> First Close Teamviewer, if it is running.

2> Click on Start –> Run –> type %appdata% –> delete TeamViewer folder

3> Delete registry folder: hkcu/software/teamviewer and hklm/software/teamviewer

4> Change the MAC Address of your LAN card, this tutorial can help you.

5> Restart your Teamviewer and you should get a new ID and also should solve the “Commercial Use Suspected” problem.

Please use the following method only if you have genuine problem. Please play fair as TeamViewer is one of the best freely available software, which I use and recommend strongly over others in the same niche. There is no substitute to TeamViewer.

  • default

    Very useful. It even was enough to remove the registry entry and the appdata-folder


  • @Default – Thanks. But I hope this method is not used otherwise, where people actually use it for commercial purpose and try to save their skin. Teamviewer is one of the best in it’s niche and I totally respect what their product.

  • Marcelo

    Hi, this method doesn’t work on Windows Vista. Do you know of a reliable method to do this on Vista?

  • @Marcelo – Were you able to find the teamviewer folder ? That’s where it keeps a list of all the entries. Frankly, this has nothing to do with the version of windows. If you were able to install teamviewer on your system, then you should be able to get rid of this problem. Please contact me if you are unable to resolve this problem and I’ll look into it.

  • Marcelo

    Hi. I’ve been able to do all the steps, but couldn’t change the MAC address on Vista SP1 nor SP2. I tried deactivating the UAC feature but still didn’t let me change the MAC addr. I’ve tested several programs to change it, from the page you referenced and alsowith the Techinitium MAC Changer, but Windows Vista seems to don’t obey to them.Any ideas?

  • @Marcelo, as someone mentioned its enough to remove the registry entry and the appdata-folder. Please try tht and let me know. In Vista there is no default ‘Run as administrator’ set so tht might be the issue. We can look into it if the registry entry and appdata folder deletion doesn’t work.

  • Marcelo

    Well, MAC addr couldn’t be changed but the folder and registry entries were deleted, and the program still remained blocked. The method worked fine on Windows XP, but for some reason on Windows Vista have probably recorded another registry key or something we are missing.
    Note that I’ve tested this with the last version of Teamviewer. This reset method works on Win XP, but not under Win Vista.

  • Jak2000


    Not worked in winvista Home Premium Sp1
    i am followed all the steps mentioned here

    any advice?


  • @Jak / Marcelo – Let me check this on Vista and get back to you guys soon. I’ll personally send out an email to you both.

  • alphonse

    Hi, i used teamviewer on some friends computer, but now i can connect and i can’t do anything there but doing refresh…left click not working at all. Is anyone know what’s the problem?

  • Hi, anybody got any news?

  • Bony Sukhadia

    i m using team viewer but i dont want any one to look on my screen when i m using it so wat shall i do for that….plz help me….”
    thats my id:

  • Thanks a lot Gautam!

    a simple solution, worked out for me
    infact TV is one of the important tool i use :)

  • Mark2009

    Fantastic. I actually have a real commercial licence but when I clone workstations the ID gets cloned too. By removing hklm/software/teamviewer and the %appdata% I can reset the ID. That’s a lot. Beforehand I always had to uninstall / reinstall tv.

  • @Mark – I had similar problem when I was working with a client. That’s when I figured this solution :)

  • HMC

    It’s simple for me. Maybe all of you can try this :
    1. Remove Teamviewer, delete folder Teamviewer
    2. Delete Registry
    3. Change MAC by RightClick on MyComputer -> Manage -> Device Manager -> Network Adappters -> Right Click on you NIC , choose Properties -> Advanced -> Click Choose “Network Address” -> Type 12digit in Value box (Ex : 001A3F25454E) -> OK -> Disable and Enable you NIC in Network Connections . Now your MAC was changed.
    4. Re setup Teamviewer and Enjoy it now .

    Good luck !!!

  • Hi there guys. Have anybody discovered how to do this on Windows Vista as I wrote on comments #3-9?

  • paul

    my team viewer will not work more then 57 seconds for some reason

    is there any way t5o reset that time and let it go back up to 5 minutes
    i ldid all these steps including the mac address change
    here is the steps i followed
    1. Remove Teamviewer, delete folder Teamviewer
    2. Delete Registry
    3. Change MAC by RightClick on MyComputer -> Manage -> Device Manager -> Network Adappters -> Right Click on you NIC , choose Properties -> Advanced -> Click Choose “Network Address” -> Type 12digit in Value box (Ex : 001A3F25454E) -> OK -> Disable and Enable you NIC in Network Connections . Now your MAC was changed.
    4. Re setup Teamviewer
    is there a way to go back up to 5 min..

    thanks in advance for the replays

  • @Paul – Interesting problem. I haven’t encountered any such problem. When I can do is, research thoroughly and see if there has been any such problem and solution for such a problem. That’s the best I can do.

  • Hi there,
    I recently used Teamviewer to resolve a programming problen with some expert or the other. I was the payer of course.
    Can you tell me how we know whether the “expert” is abusing your system thereby making me part of the problem.
    I paid him 40$ and after the finish a screen came up saying something like “thank you for not taking advantage”….or something similar

  • Gilbert

    Hi! I have a friend who downloaded TV but during installation forgot to choose the “non-commercial option” and now the program has expired. I gave her the instructions found here (to delete the TV folder from the appdata and to delete it from the registry) But when she re-installed it again, it told her that it has expired and gave her the same ID number she had before. I wonder if there is any other registry key where TV version 5 checks the expiry date.

  • Mathiu

    Hello. Did you solved the problem of “commercial use suspected” on Vista?
    I’m having that issue on Windows 7, but I think the solution for Vista will work fine for Win7 too.
    I do everything fine 100% sure. Delete TV folder from appdata, delete registry entries, change MAC with SMAC, start TV. But the ID stays the same, and the problem doesn’t vanish.
    I tried almost everything – I restarted system after cleaning the registry, I cleaned registry of ALL teamviewer entries, I searched ALL hard drives for teamviewer directories and nothing – teamviewer ID stays the same.
    On XP this solution works great, but somehow on Win7 (and Vista as stated above by Marcelo) it doesn’t.

  • @Mathiu
    Hi there, I’m actually using TV4 to conenct one computer running Vista SP2 with XP SP3, and the Windows Vista based didn’t let me change the MAC Addr by no way. I tried too many ways, even uninstalling TV and (trying to) change the MAC and finally TV is working with no restriction. I don’t know if I’m lucky because I do use it to send my homework from the office to my house, but it stays connected ok. I think TV may be probably counting how many remote ID have you being connecting to.

  • @Marcelo – thanks for posting it. These days I’m busy with personal life that I haven’t been able to test why this doesn’t work with Vista !

    I should take some time off soon and will work on a solution for it. There should be some way for sure !

  • Hochimin

    There is a free substitute for Teamviewer that is Ammyy Admin, download from .

    Just like TeamViewer, your host connects to an echo server and receives an ID. Enter it into your client id window and click connect. Like TeamViewer, all communications are fully encrypted.

  • sam

  • OCP

    Sam same issue with windows 7 and TV5. I can no longer use TV at all, even with the tips listed in the OP.

  • ahahahndreew

    I am on Windows 7 Ultimate 64bit

    What did I have to do:
    I use TeamViewer Portable
    – Changed MAC address of my “default” LAN (randomly generated with MacMakeUp)
    – Disabled Sun VirtualBox “VirtualBox Host-Only Network”
    – Installed a newer version of Sun VirtualBox
    – Opened TeamViewer and got a new ID (didn’t need to touch the registry or the %appdata% folder because of the Portable ed I use)

    The new TeamViewer doesn’t check only one Network connection but more if available, try to play with other connections and reopen TV to see a different ID.

  • hi,
    any body connect on my pc
    id and password is
    id. (605 379 950)
    password. (8939)

  • HipResurface

    Hi Experts,
    I used TV for a long time and followed the same instructions one of my friend systems. Its works perfectly. I find another tool also called Perfect Uninstaller. I am not sure how the tool will work on Team viewer License issue. I think it remove all the registry keys created by TV.

    hope this helps.

  • Eric Deeter

    Like one other person who left a comment, I mistakenly checked the “both” business & personal during setup. I’m a real estate agent. I’m thinking such use might still qualify as “personal”. But now I’m locked out. Will this process work to reset to personal use?

  • Lew Murray

    Gautam :
    @Default – Thanks. But I hope this method is not used otherwise, where people actually use it for commercial purpose and try to save their skin. Teamviewer is one of the best in it’s niche and I totally respect what their product.

    I have a different problem. When I run Teamviewer5 from a VirtualBox XP session, I can connect to remote computers but they can’t connect to me. My computer is running Linux and my only way to run Teamviewer is in a VBox session.

  • @Lew – I respect their product too and have a commercial license now and happy to have one :). I hope people do not mis use this, and since this is a genuine problem at times, may be team at teamviewer should look into this.

    As far as your problem is concerned, i’m a little lost on this. Let me search a bit online and try to find a solution if any.


  • chris

    Since we started using a proxy server at work (zscaler), I am unable to get teamviewer portable to connect to my home pc. Theres a place to enter the proxy information manually, but I have no idea of what the IP address or port are. Any suggestions on getting around this? I am using version 4x.


  • Thomas

    I use TV 5 on Vista SP1 and have problem commercial use suspect .I already sent email to TV , do not have reply .Did any body solve this problem. Pls help.

  • Anderson

    Work fine in Windows7 (Similar to Windows Vista).

    Remember to run the change mac address program with Admin privlg.

  • I never knew that, I still prefer mstsc.exe and rdesktop over teamviewer as it goes to a third-party.

  • chetan

    if go though given step ,that problem is solve?

  • For me, the following steps helped to eliminate the Commercial Use Suspected issue on Windows 7 x64 Enterprise:

    1. uninstall Teamviewer 5
    2. delete the teamviewer folder in the %appdata% directory
    3. opening regedit and deleting everything that contains the word ‘teamviewer’ (hitting F3 to search for the next string)
    4. opening device manager to change the last character of the NIC’s MAC
    5. reboot and verifying that the mac indeed has been changed using the getmac command
    6. reinstall teamviewer 5

    Now I no longer receive the warning.

  • Ron Dean

    Using TeamViewer 5 on two computers, with both running Windows XP (one computer has XP Home and the other has XP Media Center). My partner can remotely see and control my desktop, but I can’t see my partner’s desktop. At start up of TV, my partner’s computer sometimes flashes a warning about a proxy server, but it quickly vanishes before it can be read completely. Our computers are located in our two homes. We use different internet providers (both high speed). How can I reverse this situation, so that I can see and control my partner’s desktop.

  • @Ron – Your partner can reverse who’s controlling the teamviewer from his end and let you access his machine. Have you tried that option ?

  • Ron Dean

    No I haaven’t tried it. But I will try to figure out how to do it.
    Thank you.

  • @Ron – It’s pretty easy. Your partner will have an option to allow you have access his system. He has to initiate the process. If you want a step by step, let me know, i’ll pull some time and do a write up.

  • Ron Dean

    I would appreciate the step-by-step instructions. We tried to figure it out ourselves, but no success. My partner can still see my desktop, but I can’t see her desktop. I want to be able to work on her computer. She doesn not need to work on mine.

    And she says that the two blue fields are blank, but on my computer the fields contain my I.D. and a system generated password.

  • Ron Dean


    I used my other computer to run the program and to see both ends. I used the “Action” function to flip sides and it worked perfectly.

    So the real problem appears to be that my partner is not seeing the little window that says “Wait For Session”. The blue fields are blank (where the I.D. and the Password should appear).

  • james

    I used the program for one day and it worked like a charm all of a sudden second day, tonnes of problems. It will connect to other computers but the friend’s desktop won’t appear any more. I’m very very very disappointed as I’m in Asia now and try to help my wife in kids on their computers!

  • Ron Dean

    Thanks Gataum for your suggestions.

    Besides the TV problem, mMy partner was also having a problem downloading the free anti-virus offered by her ISP. Eventually she called Microsoft and the tech removed some files (but I don’t know which files). She still couldn’t download the free anti-virus, but TeamViewer suddenly began to work perfectly. Not a single problem since. We love this product!

    @Ron Dean

  • @Ron Dean – Glad it was helpful.

  • Stan

    I can connect to host computer but screen will not refresh even if I choose from the menu. Any help really appreciated or tell me where to post. Thanks

  • gabriel

    It seems to be it doesn’t work any longer with the new version of teamviewer 5.1.9290, is someone else experiencing the same?

  • Max

  • Jace zein Mira

    I want to know if there is a way to counter/avoid being under a teamviewer.?

  • @Jace – You can turn on ‘Password’ mode and do not share your password with anyone, unless you want to. That should help you. Is there anything in specific you want to know?

  • Mike

    i hate teamviwer …. starting now let me tell you why:
    i have a network based on windows 2008 server at work and a connection to internet from my home from an local isp.
    i`ve install teamviwer on my computer at home(win 7) and to one computer at work (win xp pro ….to do something remote…) now i`m dealling with a loot of trouble because of this. the computer from work after i`ve install teamviwer it has problems like: rpc server is unavailable…. cannot renew ip address, i`ve remove teamviwer form the xp comp still it cannnot renew ip address to fix this i use regedit to remove key that teamviwer has made and did not delete those key after uninstall. after this step the xp comp can renew the ip address but now after a period of time whem i try to access the xp comp from the network i have a other problem 0x80070035 the network path was not found…. the comp is responging to ping via name and ip. (after reboot is working but i cannot reboot that computer every time when it`s dissapears from the network )
    so… my advice is not to use this progrma (if you don`t want to use a 3rd party anymore use mstsc (windows remote) if you don`t want to have bigger problmes later on.

    Mike, these problems are not related to TeamViewer. Most likely you got a virus that has corrupted the RPC service on that machine. You’ll need to do a windows repair, possibly a reinstall of the OS. I’ve been using TeamViewer for years on dozens of machines and have never ran into this problem.

    How many hours before commercial use is suspected? Also I’ve had problems with uninstalling and then reinstalling. I like Teamviewer but hate having to deal with these little snags. I wish people wouldn’t misuse the product so TV would not have to put restrictions. For personal use I use Teamviewer. At work we just bought a ScreenConnect license. It was pretty cheap from what I remember comparatively to Teamviewer Corporate.

    Teamviewer 7 on windows 7 64bit doesn’t seem to reset…

  • Luiz Paulo

    The workaround works for me once, but no more.

    I use TeamViewer 7 with Windows 7 to connect my home machine from my office and control my downloads.

    I removed any TeamViewer reference in Windows Register, removed the TeamViewer folder in %appdata% and changed the MAC Address of the ethernet board. I could not change the MAC Address of the WiFi, but disable it when try to use TeamViewer.

    I think there is some other register key with another name that this new version use, but now a can´t identify. If someone will instal TeamViewer in a new machine, I suggest to use a register analyser or something similar to identify all TeamViewer´s change.

    And, please, share what you discover!!!


  • Patrik

    The reason why you’re getting the “Commercial Use Suspected” message is because you’re either connecting to A LOT of different computers all the time, or simply because you’re in a different country than the other computer (the one you’re connecting to)

  • Crazydave

    Thought I would add my experience:

    Win 7 x64

    I have previously tried to follow the instructions given but had no luck so this is what I did to get a new ID and get rid of the commercial use suspected:

    Uninstall Teamviewer

    Start –> Run –> type %appdata% –> delete TeamViewer folder

    run ccleaner on files and registry

    run regedit as admin

    backup registry

    CTRL + F to search registry for the word “teamviewer”

    delete all entries found for teamviewer in registry

    can MAC address of Lan card


    reinstall teamviewer

    All done – new ID!

    Good luck and thank to original author

  • Thanks bro, Really helped me. 100% working.

  • Aryan

    thing is you’ll have to do this on daily basis or on every pop-up basis

    Also, @chetan, he’s talking abt registry…..
    start> run> regedit

  • Thank’s for your idea,
    I find Teamviewer versi 7 start from July 2012 has change logic in ID mechanical so logic in this web doesn’t work again.
    I was find the new logic for change Teamviewer ID Version 7 Since July 2012, for detail information please click
    (or click in my name)
    So i hope you enjoy with free remote anywhere from Teamviewer

    Thanks CrazyDave!! That worked for me! I was going in circles. Thought I had got everything from registry, but obviously not. Running CCleaner was a great idea! Finally got it cleared out and a new ID! Thanks 1000X!

    Now above method not working, becoz Teamviwer Owner know every thing that we are doing. They are taking lot of information from our pc and check with lot of parameters. u can see log file

    for free use u have to purchase new pc.

    so purchase licence copy of Teamviwer.


  • Hello Everyone, The Solution Described Above Works Efficiently Only When The Problem Is Local(Our PC) And Not On The TeamViewer Server. In My Case It Was On The TeamViewer Server Side Which Had The Old Data Of Me Using Commercial Use;Instead Of Non-Commercial Use. So I Opened A File Called TeamViewer.hta( Which I Opens Up In Internet Explorer 10 And A Small Windows Opens Up Which Asks For The Type Of TeamViewer Use,I Selected 1).Non-Commercial/Personal Use And Typed In My E-mail Address. And Hit “Next”. Then Just Restart Your TeamViewer And You Are Done. No Need For Uninstalling Or Whatever. 😀


    I use Teamviewer for years….
    Here is my trick for Win xp
    Windows Registry Editor Version 5.00

    ================ Batch file ========
    del /s /q “c:\Documents and Settings\%username%\Application Data\TeamViewer\”
    deltree /y “c:\Documents and Settings\%username%\Application Data\TeamViewer”
    del /s /q “%ProgramFiles%\Team Viewer\”
    deltree /y “%ProgramFiles%\Team Viewer”
    del /s /q “%ProgramFiles%\Team Viewer\*.*”
    deltree /y “%ProgramFiles%\Team Viewer”
    del /s /q “%ProgramFiles%\Team?Viewer?\*.*”
    deltree /y “%ProgramFiles%\Team?Viewer?”
    del /s /q “%ProgramFiles%\TeamViewer\”
    deltree /y “%ProgramFiles%\TeamViewer”

    didn’t work for me

    All of these suggestions do NOT WORK, at least for Teamviewer 8. I got screwed because I worked for a company that used the commercial version and then when I left them, I could not use it for personal use.

    You may also use Aeroadmin instead. It’s a simple clone to tv but free for business use as well and works quite good.

    Hope you like it.

    @Maulik Bhuptani – Macro World Softwares
    TeamViewer detects commercial use in the following cases:
    1) You connect to more than 7-8 IDs within a month.
    2) Your total sessions duration exceed 20-25 hours per month.
    As a result you get disconnections every 2-5 minutes.

    Of course you can reset the ID all the time but it won’t allow you to use unattended access.

    To my mind it’s better to find a free (for commercial use) alternative.
    Among those that I know you may consider Aeroadmin.
