--- Comment #9 from Mikolaj Zalewski mikolaj.zalewski@gmail.com 2007-09-19 18:35:14 --- It seems that apart from having the same problem of prematurely ending the conversation like Photoshop CS2 it expect that there are at least 4 keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components . If not it crashed with a division by zero exception. If these two problems are solved or worked-around the program starts fine. I will try to learn if adding such keys to wine.inf would have some side-effects.
