I had PEX 8.5 running on an XP machine and everything worked fine.
I upgraded to Vista x64 and have struck two problems.
1st - the help files didn't work, as Vista doesn't have Winhlp32.exe by default. However, this was resolved by downloading Winhlp32.exe and making a registry change. NB: The registry changes recommended on Microsoft's site doesn't work for Vista64, it only works on Vista32.
2nd - I can't rotate any images, I get an error saying PEX cannot rotate the image. This also applies for any other modification of the image in PEX. Other software (including PI X3) has no problems modifying the image.
Has anyone struck this problem before on a x64 system?
