Hello, Does KB836982 help? And I would like to know which OS is your KMS host running. If its Windows Server 2003, please apply the below update if not yet. An update is available that installs Key Management Service (KMS) 1.2 for Windows Server 2003 Service Pack 2 (SP2) and for later versions of Windows Server 2003 http://support.microsoft.com/kb/968915 To check if any DLLs or other components are corrupt, please run System file checker tool and System update readiness tool. Regards, Zhang TechNet Subscriber Support If you are TechNet Subscription user and have any feedback on our support quality, please send your feedback here.

Hello, Yes, I finally solved it. I found that if I ran the 64-bit cmd prompt as an admin it slmgr.vbs ran successfully. No errors. Orange County District Attorney

In anticipation of adding support for Windows 8, we checked our KMS server this morning and found that slmgr.vbs is throwing errors. Running slmgr.vbs /dlv, we get an error, 0x2a 0x8007045A. Running slui.exe it shows that a dynamic link library (DLL) initialization routine failed. KMS is running fine in the background an the KMS logs are all good. Has anyone run into this before?

Hello, This problem occurs because there is a file mismatch, or the Msxml.dll files are corrupted. So, I suggest you check this article link for troubleshoot error 0x8007045A:http://support.microsoft.com/kb/836982Regards, Ravikumar P
