I have installed Premiere Pro CS3, and when I open the program it gives me the error:

"Additional codecs that are not included in the trial version of Premiere Pro CS3 must be installed"

When I say "OK" to this, it starts a codec install process, but then at 6%, quits and gives the error message:

"Installation was unsuccessful. Restarting Premiere will trigger the codec installer again. Please contact Adobe Technical Support if this problem persists"

Any ideas on how to get this to work properly?Thanks
