Calibre will not start on Win7 x64.
I have attempted every fix I could find on the forums and the FAQ, but I still cannot get Calibre to start. It pops into task manager for a split second, and immediately closes.
Any help would be appreciated, its driving me crazy.
Here is my debug -g output:
 » calibre-debug.exe -g
