I'll be interested to hear if any of you have trouble uninstalling the beta when your trial expires. I've still got the remnants of the CS4 trial I installed years ago, before I upgraded to CS5. Windows 7 can't uninstall it. I'd give it a trial myself, but I don't want to stuff up my copy of CS5. For those that have CS5 and are running this trial, are you having any problems with running both versions?
