Is this a "big" problem? I have not had this problem on ANY of my computers (both 32 and 64 versions of Vista).
The last couple of days I've been meaning to set aside some time to try it. I have downloaded the installer and when I click on it nothing happens. The process is running but it's using only 157k of memory and no dialogues ever appear.
