Recently I have been receiving lots of File Permission Errors when saving documents. I have searched the internet endlessly and have still not found a solution.

Sometimes, when I save from Word (2010) I get this error:

Word cannot complete the save due to a file permission error. 

Then I can retry, it asks me to overwrite the old file and it works.

I am running Windows 7 64 bit Ultimate.

It is also happening in other applications. Such as Photoshop (CS5), again I resave and overwrite and it works.

I get a problem in iTunes too:

The iTunes Library file cannot be saved. An unknown error has occurred

This is IMMENSELY annoying so any help is appreciated!

More information needed. Where are you trying to save to? What are the permissions assigned to that location? – Matthieu Cartier Jan 27 '11 at 19:27
How do I show you the permissions? – user65037 Jan 27 '11 at 19:45
Some Security Softwares can cause this issue, disable or uninstall the security software, see if the error stops. – Moab Jan 27 '11 at 21:40
Where do you save these files? USB drive? – Moab Jan 27 '11 at 21:43
@Moab, I am inclined to agree that this sounds like antivirus behaviour. I'd remove whatever AV is installed and see if the problem continues. – user3463 Jan 27 '11 at 22:32

Have you tried doing a system restore and seeing if you still get the same errors? Perhaps rolling it back may help.

This is a challenge if OP doesn't know when exactly the problem started, versus which restore point to use. – user3463 Jan 27 '11 at 22:31
