I have had CS4 on a fresh install of Windows for awhile but I would like to install CS3 now as well (because I feel it does certain tasks better), and use each one as needed.

However, I'm concerned about issues resulting from installing CS3 after CS4. I have heard that it may make the registration invalid, AME not work, and is you open dynamic link in CS3 it opens the CS4 version of the app. I'm mainly concerned with Premiere and After Effects, and don't mind don't installing other apps in the suite.

Has anyone attempted this? Issues? tips?


Thanks
