I have just wiped my hard disk and installed Windows 7.
I have reinstalled PPro CS4. After plugging in my serial number, loading PPro, it says it will download codecs not available in the trial version. I know that these are the HD codecs which will allow HDV projects.
I received a message similar to "... update was unsuccessful. Update will automatically trigger when PPro is restarted".
So I clicked okay, and then restarted PPro. But the update of codecs did not trigger.
Is there a manual way to trigger it ?
Yes, go to the Adobe site and order the full version.
From Premiere (or any other CS4 application), select the Help menu bar item and click on Updates. That should launch the Adobe Updater, and pull down any needed updates. As long as your installation is activated with a serial number, this should work. Barring that, you can also download individual updaters from Adobe's website; start here.
