I've also got a problem with XP crashing.
Up until this week I was using Vista, with CS4 Web Premium, I also installed the Dreamweaver CS6 extension with no problems.
However I have now switched to XP (Service Pack 2). CS4 again works fine, Dreamweaver CS6 seems to install ok, but every time I try opening it the computer crashes.
I have tried following the advice in the suggested thread without success.
I can't be the only person experiencing this problem, is there a solution or do I have to go back to CS4?
