Are you comfortable wading around in the Windows registry? If so, you can probably fix this with a quick digit change:
In the Registry Editor (launch regedit from the Run dialog), find the following key: Computer\HKEY_CLASSES_ROOT\Adobe.Premiere.Pro.Project\shell\open\command.
Once you select the "command" key, you'll see the program destination string on the right side; likely it's pointing to CS4. Double-click the "(Default)" string and change the value to to following, exactly as pasted here:
"C:\Program Files\Adobe\Adobe Premiere Pro CS5\Adobe Premiere Pro.exe" "%1"
That's with the outside quotes and everything. OK the change, and you may or may not need a system restart, but that should correct the issue. Basically the file extension (in this case, .PRPROJ) is associated with a class (Adobe.Premiere.Pro.Project), and that class points to default application. Once that's fixed up, the chain should be put back together.
Also, there is another key in: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Adobe.Premiere.Pro.Project\shell\open\command. Changing the above should change this as well, but you may want to check it.
I imagine that you probably reinstalled CS4 after you installed CS5. So it has the association attached to it .There is a "File Association Fixer v 1.0".or if you are handy with editing your registry you might be able to do it directly. The third option that I can think of is to reinstall CS5
Oddness... anybody else seeing this?
I have the same issue with Divx files on my personal computer. While my media player of choice is fully capable of playing them, I simply cannot set the affinity for Divx files to that player.
Don't know whay that happens.
Thanks Colin and Bill.
I'm relatively comfortable in the registry, though only with precise instructions...thanks for that. I'll give that a shot.
Yes, I did reinstall CS4 after CS5... I guess I've never stopped to think that it was the last app installed instead of the latest version...though couldn't we change the file association in the file properties in past Windows versions? (Maybe I never had to try to override the last installed version before and never realized that you can't manually control this between multiple versions of the same app?...)
I got started on the Premiere Pro CS5 FXPHD.com class, and realized that the Camtasia files I was generating to teach CS5 would have to be edited in PPro CS4 due to the 32 bit Camtasia codec.
...not Adobe's fault of course, but the irony was impressive...
(I think there's a fairly significant amount of Camtasia material edited in Premiere Pro out in the world as Premiere Pro being codec-agnostic, frame size-agnostic, and frame-rate agnostic enables it to handle that material very well... I hope TechSmith gets the codec ported to 64 bit at some point soon for the sake of staying current.)
Thanks Tim for the several freeby's of yours that I got from the Steven Gotz site.
