To reinstall MSN Live messenger, it has to be uninstalled first, and the right way to uninstall it, is from Add and Remove Programs OR Programs and Features option in Control Panel.

If done that way, there will be no problem at all.

But if you have just entered the Program Files and deleted the MSN Live Messenger folder, you really have messed it up. Not to worry, there’s a solution for that.
While reinstalling it, it would be giving an error that, it is already installed & uninstall it first.

Here’s what to do:

Go to C:\Windows\Installer

*Installer is a hidden folder, so just type the address in the address bar.

Once in this folder, move down, you’ll see few windows installer files.

Look for the ones between sizes 700 – 790kb. Right-Click on that file and go to its properties, then Details tab and look the Subject there.

You have to look for the file with Subject - Windows Live Messenger Setup Package.

Once found, Right-Click on that file and uninstall it.

This is it, now try to install the Live Messenger again & it’ll work.
