I downloaded the latest version of itunes. Now I cannot open iTunes. I receive this error message: The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll. Thoughts?

I downloaded the latest version of iTunes on my PC. Now I cannot open iTunes. I receive the following error message: "The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll" After pressing the "OK" button I receive a second error message: 'iTunes not installed correctly. Please reinstall iTunes. Error 7 (Windows error 127)". I've uninstalled iTunes and reinstalled to no avail. I've also eliminated the temp files (per suggestions on the trouble-shooting page) and no luck. I also tried system restore and that did not fix the problem. Any thougths on a repair?

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)

Let's try something relatively simple first. Restart the PC. Head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".

If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (Although the procedure is for Vista and 7 and you've got XP, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

B noir,

I tried your suggestions, starting with the simple one (no joy) and then the "two-page" fix. After following each step of the "two-page fix", I restarted the PC (and disconnected the network and switched off the firewall). I then tried to reinstall the iTunes that I had saved. The installation quit and I received the error message: "The installer encountered errors before iTunes could be configured." I'm not sure where to go from here... There is nothing to uninstall.
