Two weeks ago I installed the SP1 update for my SQL Server 2012 Express installation. I am running Windows 7 Professional, 64 bit. The install took a long time but completed. I just started noticing that my memory usage has climbed to 90%, which is 10.8 GB, and my CPU usage is always at least 12%.
After using Task Manager and procmon, I found out that ngen.exe is the offending task and appears to be trying to access files that it cannot find. The odd thing is that I am running the 64 bit version of SQL server and the ngen.exe running is the 32 bit version, and it is running from the v2.0.50727 32 bit Framework directory.
I tried to uninstall SQL Server and it hangs at a spot where ngen.exe is again running and trying to do something with modules in the SQL directory structure.
I have deleted the 32 bit service for the .NET framework and ngen.exe is no longer running, but I cannot get SQL Server uninstalled. Is there anything I can do to get things back to normal short of doing a clean install of Windows? Thanks for any assistance.
