Application Data folder corrupt

[Dan]

Hello,

I recently encountered a problem that whenever I try to open certain
programs (including Microsoft Office, iTunes, etc.) Windows Installer pops up
and says that it cannot create the directory for
CocumentsandSettings/AllUsers/ApplicationData. When I found this AppData
folder and tried to open it it said that the folder is corrupt and
unreadable. Any help on how to repair this folder would be greatly
appreciated as I currently cannot open many programs.. Thanks in advance!
