How To Solve TeamViewer “Commercial Use Suspected!” Problem

June 16th, 2009

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

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.

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

    Thanks

    @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.

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

  4. July 30th, 2009 at 06:55 | #4

    @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.

    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?

  6. August 2nd, 2009 at 22:09 | #6

    @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.

  7. 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.

    Thanks a lot Gautam!

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

    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.

  15. September 23rd, 2009 at 21:07 | #15

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

  16. October 7th, 2009 at 20:38 | #16

    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 – 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.
    Best,

    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

    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.

    @Gautam
    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.

  24. January 22nd, 2010 at 23:48 | #24

    @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.

  25. January 23rd, 2010 at 00:37 | #25

    @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 !

    There is a free substitute for Teamviewer that is Ammyy Admin, download from http://www.ammyy.com .

    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.

    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,

    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.

    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?

    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.

  37. April 7th, 2010 at 18:32 | #37

    @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.

    Cheers,

    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.

    Thanks

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

  43. June 8th, 2010 at 16:02 | #43

    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.

    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.

  49. July 26th, 2010 at 06:15 | #49

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

  50. Ron Dean
    July 26th, 2010 at 07:14 | #50

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