I don't know whether or not you found the solution to your problem but here's what I did:
1. You said that you're using win7 so this should definitely work
2. Just right-click on the application file and go into the properties
3. Click on the "Compatiblity" tab and check the "Run as administrator" checkbox.
However if that doesn't work, you'll have to redo step 2 but instead click on the "Security" tab and change all the permissions (for all users) to "Full control" by clicking the "Edit..." button.
The point you made about Adobe's CS products is rather pointless though, because it's been over a decade and the only apps that can compete with a program like photoshop are not even worth it. Corel has a steep learning curve with limited (well, not enough) tutorials, Microsoft's Expression Design is crap software compared to GIMP (which was great until CS4) and everything else sucks! The monopoly that Adobe has created for itself is well deserved, especially sice they are always fixing bugs when reported and providing updates almost as much as Microsoft Windows (which becomes annoying but, unlike Windows, is tolerable).
First, thanks much... it works...
I agree with everything you said except 'monopoly is deserved'. We have lots of institutions that try to prevent a monopoly for obvious reasons. We just have it with Adobe and they are way better than Microsoft but I do believe the bad press created by Apple recently has brought a slew of updates.
Again, thanks... this really helps...
It is true about the reason for the updates (because of Apple), but, Apple is primarily a great maker of physical products (Macintosh, IPod, and so on). Yes, they do make great software as well but, that's still second to a company like Adobe which is (as far as I know) only concerned with software. What I'm trying to say is, I really can't see the reason, other than their customer's satisfaction, why Apple decided to bash (for lack of a better word) Adobe.
