Will not uninstall anything!

I was tryingtoupgrade my version of iTunes when i noticed it will notuninstall the older version.

Is there any way to fix this problem? I kinda deleted everything in C:\WINDOWS\Installer and don't know how to get anything back.

I was running out of space so i deleted it.

I need to know if theres a way to fix this.

Even Ahead Nero will not do anything with installing or uninstalling.

 

Please reinstall Windows Installer.

 

u should be able to dload the installer here if need be:

Thats what i get, i got that before the installing of windows installer also

 

NEVERMIND --- I fixed it.

I used Your Uninstaller 2006 and First did a Force Uninstall and Advanced Uninstall.

I was able to reinstall it after that.
