Thanks for the additional info, BetterRed.
And may I assume that all calibre settings as placed in the the registry and the following locations:
C:\Users\DrChiper\AppData\Roaming\calibre
C:\Users\DrChiper\AppData\Local\calibre-cache
will also remain when I uninstall calibre 32-bit?
When so, then indeed the move to 64-bit might be hassle free

I always have fun when I see this directory:
C:\Users\DrChiper\AppData\Roaming\calibre\
