Awsome guys.. I had been pulling my hair out over this one and was very close to reimaging the laptop. In addition to gpedit not working I was unable to use search, and could not open windows updates. Was able to get to any other website. I was contemplating a virus or some malware of some sort. Glad I came across this link. :)

This is just the DLL's becoming unregistered, all you do is create a txt batch file, call it Fixmmc.bat or similar, then enter the following commands into the text file and save it:

==============================================
@echo off
Echo Deleting potentially corrupt files (don't error if they are missing)
CD /D %SystemRoot%\System32
del /q Msxml.dll
del /q Msxml2.dll
del /q Msxml3.dll
Echo Copying from Windows Backup DLL files
copy /Y %windir%\system32\DLLCACHE\Msxml.dll *.*
copy /Y %windir%\system32\DLLCACHE\Msxml2.dll *.*
copy /Y %windir%\system32\DLLCACHE\Msxml3.dll *.*
Echo Re-registering
regsvr32 /s Msxml.dll
regsvr32 /s Msxml2.dll
regsvr32 /s Msxml3.dll
Echo I am done, go test it out now!
==============================================


Now run the BATch file and it will fix it.

Ok

start > run
mmc
<enter>

In the empty console,

FILE > ADD/REMOVE SNAP-INS

click ADD

Select DEVICE MANAGER

ADD button, FINISH button, CLOSE button, then OK button

In the console, you should see Device Manager

FILE > SAVE AS, click the DESKTOP button on the left and save it as devmgmt.msc

Now close the mmc

on your desktop, double click devmgmt.msc

Does it open? Device manager?


hi i have exactly the same problem. managed to get to the above. click the desktop devmgmt.msc and the device manager pops out like normal. now how do i get this into my computer, right click device manager instead of on the desktop ??

what happens if you do start > run > cmd > eventvwr.msc ?
or start > run > cmd > services.msc ?

if you can't open anything ending in msc try this
http://www.dougknox....c/xp_mscfix.zip

if you can open those...but just not devmanager
try this
http://www.kellys-ko...agerrestore.reg


Hi, I found this thread searching for help on a similar error message. However when I followed the thread to this step I got a different result than the original poster.

When I tried start > run > cmd > eventvwr.msc &
start > run > cmd > services.msc respectively, they ran without any issue. So I went back and filled in the final blank with dfrg.msc (the item I'm having the problem with) and it popped the old error message again.

MMC cannot open the file C\WINDOWS\system32\dfrg.msc

I know you included info for "if that works" but with it being a different program I figured there'd be a slightly different answer.

Much thanks in advance!

EDIT:

Nevermind, this fixed it:

Ok

start > run
mmc
<enter>

In the empty console,

FILE > ADD/REMOVE SNAP-INS

click ADD

Select DEVICE MANAGER

ADD button, FINISH button, CLOSE button, then OK button

In the console, you should see Device Manager

FILE > SAVE AS, click the DESKTOP button on the left and save it as devmgmt.msc

Now close the mmc

on your desktop, double click devmgmt.msc

Does it open? Device manager?


Only subbing in dfrg.msc instead of devmgmt.msc. So, problem solved.

Thanks for not deleting old threads!

1st let me appologise for digging up an old thread but it was the only onei could find that actualy came close to my issue of being unable to open device manager

OK, interesting...since msc files are really only xml files, I'm going to take a shot here and guess something is wrong there instead of with the management console

start > run
RegSvr32 MSXML.DLL
<enter>

repeat with the following
RegSvr32 MSXML2.DLL
RegSvr32 MSXML3.DLL

report any errors

If all three report success , try

start > run
devmgmt.msc
<enter>

again


i followed the steps up to this point and the results i get are

loadlibrary("MSXML.DLL") failed - The specific module could not be found
loadlibrary("MSXML2.DLL") failed - The specific module could not be found
DllRegisterServer in MSMXL3.DLL succeeded

thanks in advance

You are the man! This was exactly what I needed. However, I did pick the right file through trial and error because there are three to choose from. The correct one starts with

msxml3

I skipped all the remedies that failed for that one user and went straight to this to try it and WALLA, worked like a charm. You have GREAT "hunch" skills! This fix repaired the trouble I was having with my IE8 browser. It was unusable. I kept getting an error report that stated something like run time error and said something about Microsoft C++ in the blue title bar of the message. I wish I could remember exactly what it said so I could pass it on...but anywayz, you da bomb!! :)
