Office Document Cache

Now navigate to the HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Internet and delete the FileStoreCriticalError key. If the key doesn’t exist then you can skip this step.


Make sure that the OfficeFileCache folder does not exist in the system. Please check the %userprofile% \AppData\Local\Microsoft\Office\14.0\ path and be sure to delete OfficeFileCache if it exists. %userprofile% is usually C:/Users/[UserName]/.

Once done, restart Office 2010 and the error should be gone. Enjoy!
