So I have upgraded to a newer faster cooler computer. Win7 to Win 10. Files moved across, Calibre seems to work fine.
I installed Calibre 32 bit on the new system, mostly to match what was on the old system and to have one less variable in the move.
Now the question is should I download the 64bit and install (presumably over the 32bit)

Are the advantages important enough to go through the effort??

thnx,
