Run the Creative Suite Cleaner Tool, then reinstall from your DVD or use the download:
Also check your system and remove any CoDec packs. The problem is most likely not that the Co_Dec doesn't exist, but that its association has been usurped by garbage liek K-Lite or whatever.
Thanks. I read the readme first pdf and am I correct that they want me to Uninstall Creative Suite (or just PPRO?) and run clean up, then reinstall software?
The uninstall is optional and really not necessary. The cleaner tool will erase al linstall information, so it looks liek nothing was ever installed and any files that exist simply be overwritten. If your PPro is part of a suite, you'll have to reinstall the entire suite.
