"setup has detected a different version of this product already installed"

Thorsten Seßler

Having purchased Trados Studio 2024, I would like to uninstall my previous Studio 2021 version before in order to obtain a clean installation. Trying to unstall Studio 2021 using the installer ("chainer") my system returns the message mentioned in the subject.

I am aware that I am not the first person to encounter this problem, so I tried the fixes suggested in previous postings--however, to no avail:

1) I renamed  the System folder to System_old in C:\ProgramData\SafeNet Sentinel\Sentinel RMS Development Kit

2)  Entering lsinit.exe –debug in C:\ProgramData\Package Cache\SDL\SDLTradosStudio2021SR2 returns to result

3) I started the the RemoveStudio.ps1 powershell script as administrator, with no result either.

What else is there to do to successfully clean my registry?

    In you email message (the content of which doesn't appear here) you suggested to either run the program "Wise Program Uninstaller" or delete the folders C:\Program Files
    (x86)\Trados\Trados Studio and C:\ProgramData\Package Cache\Trados and then try again to uninstall the program.

    Wise Program Uninstaller will return the same error message ("has detected a different version" etc.), and once I delete the package cache files, the file "Chainer" required by Windows isn't available anymore.

    So I guess I will have to look up and delete the Trados data in the registry manually.

    Either SDL or Microsoft haven't done their homework...
