regsvr32 /s Msxml.dll

Zde je originální ruční návod:
This may be because the file does not exist, is not the 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.

This issue may occur 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

To resolve this issue, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type cd %windir%\system32, and then press ENTER.

Note The %Windir% folder is the folder where you installed Microsoft Windows.
3. Type the following commands. Press ENTER after each command.
Regsvr32 Msxml.dll
Regsvr32 Msxml2.dll
Regsvr32 Msxml3.dll
4. Type exit, and then press ENTER to close the Command Prompt window.
5. Restart the computer.
