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.

(**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.

(**Update – Aug 03, 2011**)

    @Tulasi – The latest versions of TeamViewer should function without any of the above mentioned problem. Have you downloaded it yet ?

    It is working!
    Thank you!

    You may want to try Ammyy Admin
    http://www.ammyy.com

    It’s real TeamViewer alternative,free for home use but in case you want to buy paid version it will be 10 times cheaper than teamviewer.

    the registry keys are different than in step 3:
    (3> Delete registry folder: hkcu/software/teamviewer and hklm/software/teamviewer)

    should I delete the entire folder Version 7??
    commputer\HKEY_CURRENT_USER\software\TeamViewer\Version7

  7. April 23rd, 2012 at 13:43 | #7

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

    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!!!

    Thanks.

    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)

    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

    restart

    reinstall teamviewer

    All done – new ID!

    Good luck and thank to original author

    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

    @Crazydave
    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.

    thanks

    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(http://razor.uphero.com/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. :D
    Regards,
    Razor

    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. http://www.aeroadmin.com
