not sure how it happened, but trying to update I ran into problems. So I tried to uninstall to start from scratch, but that also didn't work. Now I'm stuck with the installer always asking me of for a valid installation package of "FileBot_4.9.3_x64.msi" - but even if I download that and point the installer to it, I get the same errror:

This happens when trying to install 4.9.4 as well as trying to uninstall the current version. what else could I try?
Cheers,
