Try this... seems to work for many people...
1) Make sure IE 8 is closed then navigate to registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\User Shell Folders
2) Add a new “Expandable String value” inside the above mentioned key with a value name of “AppData” and a value data of “%USERPROFILE%\Application Data”.
3) Reopen IE 8 and see if you still get the error message.
