Uninstalling Old Versions with GPO

[Dave.E]

Hello,

We are trying to move away from manual installs of TeamViewer and start deploying with an MSI through GPO. This works great, but certian computers with old versions (6&7) do not install. The 'TeamViewer 8 (MSI Wrapper)' installs fine but does not install 'TeamViewer 8'.

I am trying to find a way to uninstall the old versions with a startup script in a GPO. This way I can uninstall the old versions and install 8 in the same startup.

So far I have attempted writing a script with msiexec and a script to run the uninstall.exe but neither work.

Does anyone have any suggestions? Perhaps an MSI that will work as a silent uninstaller?

Than you!

Dave
