Fixing Corefoundation.dll

This .DLL is located in C:\Windows\System32 and is associated with Apple software such as iTunes, QuickTime, MobileMe, etc. The file could have become corrupt or there may be errors in the registry. If you are experiencing errors from this .DLL file then you should take the following steps to troubleshoot the issue...

Before you do anything... Reboot your computer! The error may not persist. Some process may have just mishandled it and a simple reboot could fix the problem. If rebooting did not fix the problem, proceed.

First, ask yourself:

• Do I only receive corefoundation.dll error messages when attempting to run a particular program?

  • It's very likely that you are only receiving this error when running a particular program that is also likely to be Apple software. If this is the case, then a simple uninstallation and reinstallation of the application will fix this issue. If it occurs when running any Apple software, uninstall all Apple software and reinstall.

• Is my computer clean of viruses?

  • I don't believe this is a highly targeted file of malware; however, it's best to be safe and run a virus scan on your computer to make sure there is nothing tinkering around with this delicate file.

If reinstalling the application(s) that were causing the errors did not work then proceed to the next step.

Now, ask yourself:

• Can I verify the presence of corefoundation.dll on my computer?

  • This .DLL may be missing or have been accidentally deleted. Let's check to make sure it's still there. Start by...

1. Double-click My Computer/Computer on the desktop

2. Double-click C:\

3. Double-click the Windows folder

4. Double-click the System32 folder

5. Browse this directory for the corefoundation.dll

Whether it is there or not, you're still receiving errors right? If you can see the file in C:\Windows\System32 then it is corrupt, if you cannot see it, then it is missing or deleted. Either way, you need a working copy of that file and there are a couple of ways you can go about getting it.

• Download corefoundation.dll

  • Follow the instructions for downloading and installing the file on this web page.

  • Don't forget to reboot your computer!

• Copy corefoundation.dll from a computer with a known working corefoundation.dll (this file is likely to be found on another computer with Apple software installed and can be found in C:\Windows\System32) It would be fairly simple to copy this .DLL on a thumbstick from it's default location and place it into the same location on your own computer. If you elect this option, you must register the file within the Windows registry by opening the command prompt and typing the following command: regsvr32 corefoundation.dll

  • Don't forget to reboot your computer!
