@rfcdvc45 - The install structure changed with version 3.0

I too doubt Defender is the culprit, but given its easy to exclude the calibre folder why not put that possibility to bed.

What it's more likely to be is a 3rd party program that runs at start up, or a Windows shell extension, running in Safe Mode will eliminate many of those.

And I've seen this a few times -- "blah blah' doesn't happen if I run calibre in admin mode -- I have no explanation for that, other than a Windows problem, IIRC in at least one instance it may have been solved with a system file scan.

And on a couple of occasions 'weird' problems have manifested in the 64 bit version but not in the 32 bit version, on the same machine - I have no explanation for that either. This is from the "calibre freezes/crashes" FAQ:

On some 64 bit versions of Windows there are security software/settings that prevent 64-bit calibre from working properly. If you are using the 64-bit version of calibre try switching to the 32-bit version.
