Somehow my c:windows\system32\rundll32.exe     is coruupt. I get this error every time I try and load certain Windows files example Add/Remove, Paint, all programs  I cannot use run.

 

I have my orginal disk and also a SP2  and I would like to just repair this error problem without having to re-install all programs.

 

I inserted my Cd rom and the "4 different posiblities come up. There is a Green arrow  by # 1 Install Windows XP  but nothing happens when I click on it. I was trying to see if there was a sub menu to repair my Windows XP Home.

 

Any idea how I can fix my Windows problem as it preventing me from accesing most programs on my computer.
