Tried to upgrade from Spybot-Search & Destroy 1.3 to 1.4 but get message "The SPYBOT.EXE file is linked to missing export USER32.DLL:EndMenu" and "Undable to execute file: C:\Program Files\Spybot-Search&Destroy\SpybotSD.exe. Create process failed code 31. A device attached to the system is not functioning"? System hangs until 1.4 is uninstalled. S&D 1.3 had been working fine with Win 95, but now it's uninstalled and I can't get it back.
