I have developed several progets on Adobe Premiere Elements 3.0. Now I've changed my OS (wwindows 10). I should install Premiere 13, but I would known in advance if progets based on 3.0 can be used with 13 without any problem.k,
There is no guarantee that any project created in an earlier version of Premiere Elements can be opened in a later one. The usual recommendation is to finish the project in the version in which it was created. And, if you do try to do this, please do that with a copy of the project from the earlier version since the 3.0/3.0.2 project edited in 13 cannot be taken to 3.0/3.0.2 to edit it again.
It is not impossible that you can do this, but because of the large differences between these versions it is unlikely to be successful. But, worth a try with the safety net of using the copy from 3.0.
1. Be working from the 3.0.2 Update of 3.0
2. Have the source media that went into the 3.0/3.0.2 project still tracing back to the project file.
Please consider. If any questions or need clarification, please do not hesitate to ask.
