In removing the software you may have deleted shared files/drivers.

Was one of the programs QuickTime? It's essential to the running of PD8.

Solution...? Ahhhhh the 64 million dollar question.

Drastic solution - reinstall your OS.

Try re-installing QT. PD might still pick up the missing drivers etc. If not try uninstalling PD and then re-install to allow it to pick up the QT stuff.

If that works - $32,000,000 to my PayPal account - cheaper than Dafydd.

As Dafydd says you may have also uninstalled other shared resources so ....

Grr. Mac software to run PowerDirector?!

But anyway, I reinstalled Quicktime & now PowerDirector is running fine. Thanks for you help. & yes, I know, my aggression against Mac's is childish

Ugh, I some how double posted...

Okay, now I've noticed I've been having trouble opening .avi files. In every kind of player I try to use (WMP, WMM, Real Player, Quick Time, PD, etc...), they always crash. Is it possible I uninstalled some else that would cause this problem? I know this doesn't have much to do with PD, but since I've already created this thread, I thought I might ask. If no one knows, I'll try a different forum site.

I know it's just this computer because those same files, (which are on an external hard drive) works fine on another computer.

In that case might be worthwhile installing/updating/reinstalling ffdshow, just use the defaults, and see if it "replaces" anything missing??

Nope, didn't work. I still can't get the videos to play. I even tried K-Lite Codec_Pack_561_Mega.exe & I still get the problem.

I have noticed a few things. The videos actually do play in Quick Time, but the quality is low (that's normal). Also, some of my .avi do work, but other important ones don't. As long as the problem persists, I can't edit the .avi files on this computer in PowerDirector.

Any other suggestions?

Update:
lol, well this kind of makes me laugh. I just saw that the new patch was out now. I installed it & now I can play/edit my AVI files again! But WMP, WMM, & Real Player still crash on me, so the problem still persists. But at least I can edit again!

Oh, & am I working on the problem on another forum site:
