Makes the install of Alcohol 52 fail

Hello,
I've just bought a new Windows 7 PC and when I tried to install Alcohol 52% on it (and I've encountered on the web other users who had the same error message with Deamon Tools so you should check this one too) all my attempts were failing with an error "Internal Setup Error".
Because most of the people who succeeded to fix this issue did so by uninstalling some anti virus or anti malware software, I started by trying to stop the services of your software (I had installed your beta 4 of SS&D 2), but the issue was still here. Then I tried to uninstall you software... and this time the install of Alcohol 52% worked !
So, I guess this would avoid a lot of trouble to some of your users if you could :
- at least inform them of this incompatibility
- or, even better, find a way to avoid this problem (adding Alcohol 52% on a white list ?)
I hope this would help you to improve your software and also help users of Alcohol 52% (and Deamon Tools since it seems they experienced exactly the same issue).
