Microsoft recently released ConfigMgr 2007 R3 Beta, and it has been available for download at Microsoft Connect.
However, there seems to be some problems installing the beta for some users, including myself. What happens is that when trying to run the installer there is an error message saying that the evaluation version of ConfigMgr SP2 or higher is required, and it simply won’t install.
The weird thing is that the logfile for the R3 Beta install says that R3 is already installed, which threw me off.
Logfile says following:
Property(C): SmsDetectDowngrade_ErrorMessage = A more recent version of the application is already installed. Setup will now end.
Property(C): SmsDetectUpgrade_ErrorMessage = Configuration Manager 2007 R3 is already installed. To install this version please uninstall the previous version by using Add or Remove programs.
Since I didn’t have R3 installed, and had the required “SP2 or higher”, I immediately figured that the installer was broken and contacted Microsoft to report the issue.
After the Microsoft technician had talked to the ConfigMgr production team, he answered the following, which clears things up.
This basically means that you can’t install the R3 Beta in a production environment, and need the actual evaluation version of SP2 (as the error message clearly states) to install it.
