This is like a flat time and no spare.
You can still try the old SFC /SCANNOW noted at http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/system_file_checker.mspx?mfr=true and hope.
I have a laptop running windows XP and SP2. Looking around it appears to have a problem with rundll32. It can't find the application, however it is there on the machine.
XP came installed with the laptop so I don't have the original source CD, only recover CDs for reinstalling XP.
Due to not being able to launch any applications I can't get AVG running to perform a complete virus check.
Can anyone provide any assistance in how I can resolve the issue? I'd rather not perform a complete reinstall of XP if I can help it, but if it comes to that then so be it.
