When I try to "Add/Remove Programs" in the Control Panel, mshta crashes with "mshta.exe has generated errors and will be closed by Windows".
I have tried the Microsoft suggested solution (running sfc) and another suggestion I saw here of running "regsvr32 appwiz.cpl". Neither have any effect.
I have tried re-installing Windows from my CD but I'm told I can't reinstall SP2 over SP3.
So what now?
