I ran the edition upgrade on a SS2005 installation to bring it up to 2008 R2. Now I am seeing two identically named instances (MSSQLSERVER) when I run setup again. Not only the instance name, but also the details (version, edition, installed features) are
I tried running a repair on the first "instance" and got a file locking error that crashed the setup. Rebooted, then tried again, this time on the second "instance". Same error:
The process cannot access the file 'C:\Windows\SysWOW64\perf-MSSQL10_50.MSSQLSERVER-sqlagtctr.dll' because it is being used by another process.
Background: Reporting Services had been misconfigured, so I was going to uninstall and reinstall SSRS; that is why I had gone back to the setup program. This is Std x64 Edition, running on Server 2008 Std.
