Hi!
I run a W7 x64 implementation and, until today, I hadn't realized that there actually
was a x64 version of Calibre going around.
So I installed it and it works like a charm (usually my system froze for about 10 seconds while Calibre loaded, now that's gone

), but I want to uninstall the x32 bits version, but I'm afraid I might break something and I've invested a lot of time organizing my library just to blow it up due to careless uninstalling.
Is there anything I should keep in mind or do before uninstalling the x32 bits version from my system?
