I cannot open folders in the control panel. I keep getting this error message:

missing system32/rundll32.exe. I bought regcure and run it constantly, it hasn't fixed the problem.

I've used my Mesh Recovery disk, located rundll32.exe and put it in the folder, but it still doesn't recognise it and I cannot open the items, Add/Remove software etc.

Anyone know of any other solutions, this one is driving me crazy.
