Uninstallation of SCVMM2012 SP1 fails with error 1603

Hi all,

I have the following situation - a single box with SQL2012, SCOM 2012 SP1 and SCVMM2012 SP1 (connected). As I am upgrading to VMM 2012 R2, I had to uninstall the VMM 2012 SP1. The issue is that the SP1 setup fails with error 1603. Before uninstalling I removed the VMM rollup update (there was only one installed). Here is part of the vmmserver.log file I think is somewhat relevant:

MSI (s) (40:F4) [21:33:23:983]: Invoking remote custom action. DLL: C:\Windows\Installer\MSI12C7.tmp, Entrypoint: DisableWsmanCredSSP
Action start 21:33:23: DisableWsmanCredSSP.
CustomAction DisableWsmanCredSSP returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

I tried the following cmdlet - disable-wsmancredssp -role server and disable-wsmancredssp -role client but setup still fails with the same error.

I hope someone can enlighten me regarding this as now I don't have any VMM working :D

Thanks in ad

I ended up having to manually uninstall SCVMM SP1 by removing folders, services and registry keys. Once that was done I was able to install R2 successfully.

Hi,Would you share the exact keys and folders you removed? I was going to rebuild the server...

I too am seeing this error.  I was using Windows 2012 Server with SQL2012 installed locally.  I had installed SCVMM 2012 with SP1 included, then applied Update Rollup 2.  No further URs had been installed.  The SCOM 2012 SP1 console was installed on this system for SCVMM/SCOM integration.

I was attempting to upgrade to VMM 2012 R2, so I chose to uninstall VMM server but retain the database.  I too had to uninstall UR2 due to experiencing problems described here:

Also having the same problem.  I cannot uninstall SCVMM 2012 SP1 Management server in readiness to upgrade to SCVMM 2012 R2.  I have researched and tried everything and nothing works :(

I rebuilt the server eventually :) I hate such "solutions" but after all I needed it working.

The issue is related to Windows Assessment and Deployment Kit (Windows ADK) 8.0.

In my case I had ADK 8.1 installed over VMM 2012 Server recently.

I had to reinstall ADK 8.0 to be able to successfully remove VMM 2012 Server.

Solved by simply enabling wsmancredspp.

From an elavated PowerShell run:

  • Enable-WSManCredSSP -Role server

But anyone know what causes this to happen?  It pretty much tanked my VMM installation, and service wouldn't start.
