When you use the Regsvr32.exe command-line utility to try to register the Msxml3.dll file in Microsoft XML 3.0, you receive the following error message:
DllRegisterServer in mxcml3.dll failed. Return code was: 0x80070005
Additionally, you may experience some problems after the registration process fails. For example, you may be unable to run Microsoft Management Console.
This problem occurs if you use a non-administrator account to log on to Windows. For example, you use an account that is a member of the Power Users group.
This problem occurs because the registration process was changed in Microsoft XML 3.0 Service Pack 7 (SP7).

To work around this problem, use an account that is a member of the Administrators group to log on to Windows, and then reregister the Msxml3.dll file. To register the Msxml3.dll file, run the following command:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
As a safety precaution, certain third-party applications try to reregister the Msxml3.dll file. In earlier versions of Microsoft XML 3.0 than Service Pack 7, members of the Power Users group have sufficient permissions to reregister the Msxml3.dll file. In Microsoft XML 3.0 Service Pack 7, the registration process acquires Full Access permissions to the Microsoft XML 3.0 registry subkeys. The process fails when non-administrators try to register the Msxml3.dll file. This hotfix gives the non-administrator accounts Read and Write permissions to the Microsoft XML 3.0 registry subkeys.
The version number of the Msxml3.dll file in Microsoft XML 3.0 SP7 is 8.70.1113.0. Microsoft XML 3.0 SP7 is installed together with the security update that is described in the following Microsoft Knowledge Base article:
924191 MS06-061: Vulnerabilities in Microsoft XML Core Services could allow remote code execution
Note This hotfix only affects reregistering the Msxml3.dll file. To install or to upgrade the Msxml3.dll file, you must log on to Windows by using an account that is a member of the Administrators group.
