Office Outlook 2003 Error message - The operation failed due to an installation problem

Error messages such as the above can sometimes occur if you create a new user and try open outlook express. You may find, however, that outlook express is fine for other users.

(You should back up your registry before doing this, just in case!)

Got to Start and Run and type in regedit and click OK
Go to HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common
Right-click on "Common" and choose "New". Choose "DWORD" Value and name it "UserData"
Double click on the DWORD (UserData) and set Value data to 1

Close the Registry Editor and open Outlook again

If this does not work try the same in the Office folder beside common

I.E HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\outlook

Best of luck
