Can anyone tell me PGP WDE 9.10 compatible with Windows 7 Professional 32 bits and 64 bits? If not which version I need to upgrade to? Thank you.
Windows 7 support started in 9.12, so you should at least go to that. I believe Symantec are ceasing support for 9.x soon though (don't quote me on that), so you'd be better going to 10.x if you can.
