I was using Msn Messenger 7.5 which I accedently got uninstalled.

While reinstalling it, my PC was struck by a power failure when the installation was right in the middle.

Now when I try to install it I get an error message that "C:\WINDOWS\Installer\{CEB3A11A-03EA-11DA-BFBD-00065BBDC0B5}'. A file with this name already exists. Please rename or remove the file and click retry,or click Cancel to exit."

I`ve tried to browse for the folder "C:\WINDOWS\Installer" but i`ve come to know that the folder "Installer" does not exist in the directory Windows. I`ve even searched the hidden files but no use.

Please tell me wat can I do to install messenger now.
