I've been using this gem for ages and ages -- even sent the author some compensation for it out of gratitude. But when I very recently upgraded from 64-bit Windows 7 to 64-bit Windows 10, the nightmare began.
Updating to Calibre 5, I found I couldn't even read many of my books let alone convert them. There was no DRM present in any of them. And yes, I also updated to Python 3 in Windows path...but still no go.
I finally reverted BACK to Calibre 4.23 with Python 2.7 in Windows 10 (after completely uninstalling version 5.x and Python 3), configured it as I always have but now can only read and EDIT my ePubs and AZW3 books...NOT convert them to another format! Any of them -- even books that I scanned myself that never contained DRM. I hope I'm not breaking any rules but here is the error message I get when trying to convert from one format to another:

Can anyone
please help me with this? I've been using Calibre since almost day 1 and nothing like this has happened before throughout all my Windows upgrades. I've spent sleepless nights on this issue with no luck.
