Today I started installing SCCM 2012 Beta 2 in my test environment. while I was installing the Central Admin Site, the installation wizard got stuck at “Evaluating Setup Environment” step and the following errors were logged in C:\ConfigMgrSetup.log:
ERROR: Failed to write string -T8295 to registry on SQL Server
ERROR: Failed to write string “-T4199” to registry on SQL Server
This is because the SQL Server service is not running under Local System. After I changed the SQL Server service to run under Local System, restarted SQL Server service, the SCCM 2012 setup went successful!
This is documented in “Configuration Manager 2012 Beta 2 Supported Configuration”.
