Well, not so. I've switched to 64bit perhaps two years ago and always downloaded the 64bit-installer since then. Had no problem upgrading ever. But you may be on to something, it turned out that the applications administration in settings somehow knew 2 calibre-instances - so perhaps there were remnants of that in the registry.

Meanwhile I'm back in business but it was really hard work as I couldn't live with all individual settings set back to default.

What I had to do is to make a complete emergency-backup of the current corrupt situation, then re-install my last system-backup (losing about 2 weeks of progress) and start working v5.44 from there. Then I used the export function to save all calibre-content to a different folder. Now I could re-install the current situation from my "emergency-backup". Then - as you already suggested - I performed a complete uninstall first. And after performing a custom-install to my old path (which now had become available again) I could finally import the backup-folder made from the previous security-backup again.

Quite tedious - but I'm up and running again. Thanks for the advice though.
