Operating system: Windows Vista Home Premium Service Pack 2 32 bit

Long story short I was manually trying to root out a virus that was infecting the windows installer files <not understanding their significance at the time> and removed just about all of them from the c:/windows directory. As near as I can determine I succeeded in eliminating the infection but, as seems obvious enough now, doing so essentially killed my capability to install or uninstall anything that doesn't use an independent ".exe" installation method. I did attempt to download the files from Microsoft's website however it seems "Windows Standalone Update Packages" can't be run without the installer files either. I fully realize this is my own fault for blindly wrecking important files but I would still appreciate any help repairing my mistake.

Did you delete the files from this folder C:\windows\installer ?

If yes we dont have any fixes.Try a system restore and see if that helps.

You could try running sfc /scannow, which may replace missing/damaged system files.
