Windows Installer has stopped working!

Since this afternoon I have a problem that messes up my laptop!
When I try to install something with Windows Installer the only screen I see is the preparing and then nothing.
Suddenly a screen pops up with an error that says something like: "Windows Installer isn't registerd" or "Windows installer is wrongly installed"

So you all know what is comming! HOW TO SOLVE THIS?

 

Reinstall Windows.

I think nobody knows what file Windows Installer is.

And can you stop breaking stuff please

 

I didn't know you could download that? lol

 

Will this also work on Windows 7?

 

I think so.

Try it, and if it doesn't Loony will come back to you (I ain't, that's for sure).

 

This problem is solved so a mod may close it!

 

Other people may have the same problem as you were having.

 

lol, reinstall windows installer. That just sounds funny.

 

I needed to remove it and all the register keys! After that I needed to install it again!
I found it on a Dutch forum!
