Hammad,

Check to see if your Windows Installer service has accidentally been set to "Disabled".

Here's how:

Right-click on My Computer and select Manage.
Expand Services and Applications and click Services.
Search the list for Windows Installer and verify it is set to "Manual".

These steps work correctly on XP Professional, but I haven't tried it on XP Home, so I hope I'm not sending you on a wild goose chase!
