RC1 is available for download. I tried that and it solved the problem.

Again the same unfortunately (I also added SMSadmin as a user in SQL Server, otherwise I got the error only SQL Server 2008 SP1 was supported, which seems to be the error you get when the SQL server is unreachable).

Thank you for your answer. To quote myself: yes, I indeed added the computer account to the local administrators group and I use the builtin domain administrator account which is also a member of local administrators. This is the local administrators group on the server on which I try to install SCCM (on which - as I said - is also SQL server). I'm sure this is all completely unorthodox from a security standpoint.

My setup is: Server1.contoso.local - this machine is only being used as a DC, nothing else. Member1.contoso.local - On this machine is SQL server 2008 + SP1 + cumulative update 14. I try to install SCCM 2012 beta 2 on member1 but keep getting errors about administrative rights. From what I have read you are only supposed to get such errors when the SQL server installation is on another server, but my SQL installation is on the same machine on which I try to install SCCM. Nonetheless, I already added the member1 computer account to the local administrators on ... member1 (I don't know whether this makes any sense but just to be sure). The account which I use to install everything is the default domain admin account named administrator (I think this might not be be the best idea from a security standpoint but this is a test setup and I don't want to make things unnecessarily complicated). The log, which sometimes is more revealing, says this: I don't know what I'm doing wrong. Anyone?
