Fix SCCM MP Uninstall Error 1603

Error code 1603 translates to fatal error that occurs during installation. Error 1603 is a generic error and often related to MSI installation failures. So what is causing the MP uninstall error 1603 ?. The answer is the configuration manager client agent. I don’t want to say that you shouldn’t install the client agent on a management point server. However in my case, the SCCM client agent was actually installed and working fine but it was blocking the mp.msi install.

On the server running management point role, I uninstalled agent using command ccmsetup.exe /uninstall. This uninstalled the client agent and deleted it’s related directories. Performed a server reboot and attempted management point role install. This time I could see the management point role was installed successfully.

It is very important that the client agent has to be removed completely. Sometimes the client agent doesn’t get uninstalled properly leaving it’s components in WMI that further prevents the MP install or uninstall. In addition to the client agent uninstall command, you can run the below PowerShell command on the server to remove all the left over traces of CCM in WMI.

Get-WMIObject -namespace "root" -query "SELECT * FROM __Namespace where name = 'ccm'" | remove-wmiobject
