I have a problem with regedit.exe. When I try to run it (regedit or regedit.exe, doesn't make any difference), only an error message appears, saying that this is not a valid Win32 application.
I have no other files named like regedit.com or regedit.bat. I've run several antivirus checks with no result. I've tried to repair Windows (XP, SP2), I've tried to reinstall them and I've also formatted the whole disk and install fresh new system (Windows XP SP2 again). Nothing helped. I have now only the Windows installed, the Comodo firewall, Avast antivirus and Firefox. Still, not valid Win32 application...
Has anyone any idea what might be wrong? Thanks.
