USE THESE TIPS AT YOUR OWN RISK! As of writing this tip, PP10 Pro appears to work under Windows 7 Ultimate Edition (both 32-bit and 64-bit). I installed the setup as Administrator. I selected complete install. I then installed both of the patches. Then before launching the first time, I configured Compatibility mode as: Check "Run this program in compatiblity mode for:", and then select "Windows XP (Service Pack 3)" or "Windows 98/Windows ME". Both seemed to work for me. Check "Disable visual themes" Check "Disable display scaling on high DPI settings" ...and check "Run this program as an administrator". In short you want to disable as many of the visual system effects as possible and run the program in the highest privlages possible for correct operation. I also recommend you install both of the patches before even attempting to run PP10 Pro after installing. Even with all of this, there are still some odd crashes happening and just like under Vista, text insertion is buggy and for optimal results should be done through the Advanced text editing option, instead of directly on the image. You might also want to consider running the softare in the Virtual PC XP Emulator mode as an alternative, but your milage may vary.
