I recently installed a fresh copy of win Xp pro with SP2. All went fine. After a few weeks I tried to open outlook express but I couldn't. It showed me an error that the file msimn.exe is missing. I tried to install OE from add/remove windows progams but still the OE folder in program files remains empty. The XP pro cd which i have is perfectly working as I have used it before also. I have backed up the message stores files(.dbx) from my previous OE. What might be the problem and how can I install OE from the XP cd?
