One common mistake most people commit while installing Teamviewer on their system is that, they forget to select the option ‘For Personal Use’ and instead install with the default option ‘For Commercial Use’. As a result teamviewer stops functioning after a couple of days from installation. Even though you are genuinely using it for personal use you’ll no longer be able to use Teamviewer.

Here’s a solution to fix this problem :

1> First uninstall the copy of Teamviewer from your system. This can be done with free uninstallers or by using Window’s default ‘Add or remove‘ program which can be found at: ‘Start’ –> ‘Settings’ –> ‘Control Panel’

2> Click on Start –> Run –> type %appdata% –> delete TeamViewer folder and also delete “C:\\Program Files\\Teamviewer”

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

4> Refer to this tutorial to change the MAC Address: http://www.irongeek.com/i.php?page=security/changemac

5> Clean your systems registry – you can use a free registry cleaner for this purpose- http://www.techbuzz.in/how-can-i-clean-my-computer-registry-for-free.php

6> Once you have completely wiped out Teamviewer out of your system – install a fresh copy of Teamviewer. Ensure you select the option ‘Personal Use’ (I’m assuming that you are playing fair here) !

    The Teamviewer remote server version 8 seems check user pubblic IP. If is it static is not possible bypass this problem. This is only my idea.
    Unfortunately seem the unique way is the crack, but is not a good idea. I use Ammyy Admin now, but is not good as TeamViewer.

    — check this path (windows vista) and delete this folder (use unlocker software) then delete registry ,restart and install (don’t select run when installing)

    click start –> run –> click on edit –> scroll down to find( look for Team Viewer)press F3 for going next on the search(once you have deleted all that says Team Viewer, search for TV ,and delete everything that has TV(in the beginning). :)Just hope you don’t any wrong file.After that just reinstall TV you will have a new ID and 7days connection(If you installing Trial Version). Trial vision gives you unlimited connection time 😀

  38. i guess these noobs didn’t follow the instruction. it is worked for me on Windows 7 Ultimate x64. I guess i installed personal only and business that cause trial being expired.

  40. You can do step 3 by doing the following:
    Start – Run – type “regedit” and browse to the location Hkey Local User / Software / Teamviewer and then delete the folder.

    I Did this tutorial without changing the mac on Windows 7 Professional. And it worked perfectly :)

    Thank you very much!

  41. Hi, how to do the step 3? Where should I go to delete the reg folder?

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

  43. Does anyone know how to re-install but with personal use only on a MAC.

    I have tried to remove the app and delete com.teamviewer.settings.plist file. Then re-install, but it still comes up pre-configured and I am not able to control the desktop from a remote site. What am I missing.
