Have a genuine 64 bit version. This one does have a bug. When i try to open a file using the inbuilt file browser, the program crashes on my Windows 7 64 bit.
You must have installed a codec that conflicts with ZP-
Try finding which module crashed.
Most commonly in this case, you installed 2 versions (x32 and x64) of the codecs..
This should have nothing to do with ZP, which supports Win7 x64.
