I have read that each version of Premiere Pro is a distince install, into a separate folder
So, you may have CS5 and CS5.5 installed at the same time, and neither one gets in the way of the other
As far as I know, that means that CS5 will ONLY look for and use the products installed in the CS5 area
So, no, I do not think any part of CS5 will work with any part of CS5.5
Iry Import Premiere Pro Sequence within AME.
Not sure if it will work, cant test it.
The short answer is no (at least not when you start out from PP)
