So, I uninstalled System Center Configuration Manager Technical Preview 3 last night. The uninstaller said it was successful, however when attempting to install the newest technical preview on the same machine, I was met with the following failures:
- Remote Differential Compression is needed, Well, this is already installed and has never been a problem before on this machine.
- Previous components are still installed from an earlier installation of System Center Configuration Manager.
Really?, the uninstaller said it was able to uninstall everything, I even went into the registry and deleted anything related to SMS or SCCM tp3.
So, this was of course very annoying and I spent a couple hours trying to solve this problem, by reading the logs, and hunting through the registry, but after searching the web I found posts that suggested starting the RemoteRegistry service, and although I had it set to start automatically, it must have not started itself, so I just went and started it, now I am installing.
Update: even after starting the remoteregistry service install still is stuck with the same two prereqchk errors
this is still not solved…
