regedit.exe isn't valid application Win32

Hello,

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.

your computer has/had a virus. Many viruses replace the executables and link to run most system utilities and tools that might be used to stop them including the program regedit.exe

My advice is to use an antrivirus, to clean the virus.

Thanks for the reply, but I think you even didn't read what I wrote. I formatted the disk and didn't connect to internet after that - and it still remained the same.

its quite strange that even after formatting it behaves like this!!

do a search for keyword regedit on system drive

and tell me how many files exactly you see after search is over?

also download CCleaner and click on registry icon there and click on "Scan for issues" button it shold fix it and reboot

I have read your post. Please make sure your antivirus is updated, and then do a full system scan.
I also advice you to scan the media from which you installed the Comodo firewall , Firefox and the Avast antivirus.

Also, if you have another partition that is not formatted when formatting the system, it might be infecting your installation again.

Another possibility (which I think is remote, it that the Windows installation media had the file regedit.exe corrupted), in this case you need to get that file from another operating computer or other media.

Already searched - three files, regedit.exe and the others were some help files.
I'l try the CCleaner and report back.

So, I downloaded and ran the CCleaner, it found 11 problems and fixed it. After reboot the problem still remains.

I also tried to copy the regedit.exe from another computer - I ran it on the other computer, it works fine there, but after copying it on my computer it gives the error. Very strange.

I checked the computer with full scan with Avast antivirus and Comodo Antivirus, no problems, no viruses.

I'm really desperate, it looks like the problem is maybe somewhere else and this is only the result...? But there is nothing else installed, no viruses, at least what the antiviruses say...

Hmm, mine is 132 KB.
I also tried to run regedt32, but it does nothing, it just appears the cursor with hour glass for a second and that's all. As I read somewhere, regedt32 is some kind of upgrade of regedit.exe (it calls regedit.exe internally).

Could you send me your regedit.exe to jjeffrey@seznam.cz? I would like to try yours, and hope it will work...

Gee, thanks! Your regedit works. I don't understand what's with mine, must be corrupted already on the CD...
Thanks very much :-)
