[gumbaz]

so whats i gotsta do now to fix this ERROR: Class not registered. thing..
what does that mean anyway, how do i register it then..??

[contrex]

If this has just started, it looks like your registry has got mangled somehow. I wonder if a virus did it? Have you been fooling about with the registry?

[gumbaz]

Nah man, I don't fool with me registry..
I remember a while back the first time i tried to use the TASKLIST it gave me the same error on dis PC.. so i just forgot about it..
but it works on all my other PC's though.. same OS and everything too..
And I never get nor have i ever got a virus.. ever foo 
I use ZA ISS like a paranoid crack head..!!!     

Anyway is there a solution to FIX  this ERROR or what..??

Search for tasklist.exe on your system, note the location, and try downloading a fresh copy from -- guess where --

http://www.computerhope.com/download/winxp.htm

and see if it works. If not, do a google search for "class not registered" errors and learn a bit about what they are and how to fix them.

If a search does not find it, well, that's the reason for your problem, and you should put a copy of tasklist.exe in a folder on your PATH.

You're sure you aren't using XP Home, which does not have tasklist? Also, some viruses disable it.

[gumbaz]

yes im 100% sure i have xp pro man...
i did do a goggle search but couldn't seem to find anything specifically about TASKLIST ERROR: Class not registered...
thats why i asked here...
xp search finds C:\WINDOWS\system32\tasklist.exe

[gumbaz]

i dunno man, i can't seem to find anything bout re-registering it back in..
so i take it you don't really know either then..??

[contrex]

That's about the size of it... I suspect your registry has got corrupted, or maybe tasklist.exe has got infected with a virus. (I do know that can happen!)

Tasklist.exe is a command line executable, and does not need to be registered, so something is wrong with your system, or registry.

there are 2 locations of tasklist.exe...one is in system32 itself, the other in the dllcache directory under system32.
You can verify their integrity by downloading fciv

To use it:

Code: [Select]

C:\WINDOWS\system32>fciv -add tasklist.exe
//
// File Checksum Integrity Verifier version 2.05.
//
70363a3228df8fc8cff4e78f36b31c45 tasklist.exe

C:\WINDOWS\system32>cd dllcache

C:\WINDOWS\system32\dllcache>fciv -add tasklist.exe
//
// File Checksum Integrity Verifier version 2.05.
//
70363a3228df8fc8cff4e78f36b31c45 tasklist.exe

If your checksum is the same as mine....then you have a clean copy. If not, then...well...try to clean it up using whatever means you have (eg AVs,Spyware removal whatever) , then install a new copy of it from the link given by contrex

[gumbaz]

*censored*.. this is weird, i just went to check my  C:\WINDOWS\system32\dllcache folder and it was completely empty..??
what would cause that..?? I have my folder properties set to show everything too..

also i downloaded a new copy of TASKLIST.EXE  and put them into their proper places.
then i downloaded that fciv.exe
ran that code in CMD  and this is what happened...

Code: [Select]

C:\>C:\WINDOWS\system32>fciv -add tasklist.exe
'C:\WINDOWS\system32' is not recognized as an internal or external command,
operable program or batch file.

^^^^
What's this supposed to be?


What are you typing at the prompt? Have you been doing this all along??? With Tasklist?

No wonder you've been having problems

That first section looks like the command prompt 'C:>' starting line, and he's just copied and pasted what ghostdog has suggested instead of CDing to the directory and inserting the command after the '>'.
