I have the exact same error after upgrading to SCCM 2012 SP1 with SQL Server 2008. I came up with this workaround: Check BgbSetup.log for the location of RegSvcs.exe: <02/01/13 17:10:35> CTool::RegisterComPlusService: run command line: "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegSvcs.exe" /u "G:\Program Files\Microsoft Configuration Manager\bin\x64\microsoft.configurationmanager.bgbserverchannel.dll" <02/01/13 17:10:38> CTool::RegisterComPlusService: Failed to unregister G:\Program Files\Microsoft Configuration Manager\bin\x64\microsoft.configurationmanager.bgbserverchannel.dll with .Net Fx 4.0 <02/01/13 17:10:38> CTool::RegisterComPlusService: run command line: "C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegSvcs.exe" /extlb /tlb:"G:\Program Files\SMS_CCM\microsoft.configurationmanager.bgbserverchannel.tlb" "G:\Program Files\Microsoft Configuration Manager\bin\x64\microsoft.configurationmanager.bgbserverchannel.dll" <02/01/13 17:10:40> CTool::RegisterComPlusService: Failed to register G:\Program Files\Microsoft Configuration Manager\bin\x64\microsoft.configurationmanager.bgbserverchannel.dll with .Net Fx 4.0 <02/01/13 17:10:40> Cannot register BGB server channel DLL G:\Program Files\Microsoft Configuration Manager\bin\x64\microsoft.configurationmanager.bgbserverchannel.dll.
