Computer Management

Question

When I attempt to open Computer Management(compmgmt.msc). I get the following message. "MMC cannot open the file C:\WINDOWS\SYSTEM32\COMPMGMT.MSC.

This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file.

The files are in the \windows\system32 directory and I am logged on with admin. rights.

This is the only administrativetool that seems not to work, all others are fine. Any help would be appreciated. If you need more info please let me know.

Thank you in advance......Lou

Answer 2

Hi,

You might get this error message when one or more of the .dll files that are used by the Microsoft Management Console (MMC) are missing or corrupted. These files include the following:

•Msxml.dll

•Msxml2.dll

•Msxml3.dll

These file might go missing or corrupt because of some virus or some third party software’s install on your computer.

Follow these steps and check if it helps:

Method 1:

1. Click on start, type command in start search box.
2. From the program list, right click on the command and click on run as administrator.
3. And type this command regsvr32 msxml3.dll and hit enter.

Method 2:

I would suggest you to try running system file checker and check if it fhelps, here is the link:

Hi Azam

Followed your instructions, Method 1 had same results. Using Method 2 Under "If the System File Checker tool cannot repair a file, follow these steps:" Step 3. Type the following command to replace the file with a known good copy of the file:

Copy <var>Path_And_File_Name_Of_Source_File </var><var>Path_And_File_Name_Of_Destination</var>

<var></var>

<var>Where do I find a good copy of the file?</var>

Answer 5

Had the same issue on Windows 7 x64.

Running Regsvr32 Msxml3.dll with admin rights did not help.

The following solution helped.

1. Take ownership and delete registry key: HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}
2. Export the registry key from another PC with the same O.S. to the registry file. Other PC I have access to, had the following registry key structure:

Windows Registry Editor Version 5.00[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}]@="XML DOM Document"[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\InProcServer32]"ThreadingModel"="Both"@=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,\  00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,73,00,\  78,00,6d,00,6c,00,33,00,2e,00,64,00,6c,00,6c,00,00,00[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\ProgID]@="Microsoft.XMLDOM.1.0"[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\SideBySide]"RegVersion"="6.0""Version60RefCount"=dword:00000001"RefCount"=dword:00000001"Version30RefCount"=dword:00000001[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\TypeLib]@="{D63E0CE2-A0A2-11D0-9C02-00C04FC99C8E}"[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\Version]@="1.0"[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\VersionIndependentProgID]@="Microsoft.XMLDOM"[HKEY_CLASSES_ROOT\CLSID{2933BF90-7B36-11D2-B20E-00C04F983E60}\VersionList]"6.0"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,\  25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,73,\  00,78,00,6d,00,6c,00,36,00,2e,00,64,00,6c,00,6c,00,00,00"3.0"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,\  25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,73,\  00,78,00,6d,00,6c,00,33,00,2e,00,64,00,6c,00,6c,00,00,003.
