Hello, today upon starting Stdio 2017 I received a message warning me that an update was available and offering to install it. I went ahead with it, but after a lengthy download and install process, eventually the update failed. When the installer tried to roll back the changes carried out until that moment something went awry and now I have lost Studio 2017.

If I try to re-install from an older installer I have saved on my machine - SDLTradosStudio2017_SR1_6278 - I get the message that "Setup did not complete. The error is: Setup has detected a higher version of this product already installed. If you wish to install this version, you must remove the other version first."

Obviously, I can't find any way to remove the "higher version" or to re-run the update that failed, so I'm currently stuck. How do I get out of this situation?

Any contribution, highly appreciated.
