I've just "fixed" a longstanding Rundll32.exe problem by simply copying the program from another machine onto mine. Now I get a new error message when I try to access the control panel: "The Rundll32.exe file is linked to missing export Kernel32.dll:ActivateActCtx." So I tried to do the same thing -- i.e. copy the Kernel32.dll from the same machine I had gotten the Rundll32.exe from. But when I opened the floppy on my computer it didn't even show the file as having been copied. Very strange. Has anyone else come across this error message and if so did they have any success in repairing it?
