I'm trying to re-install SQL Server 2012 Enterprise on a laptop that had an expired Trial edition. Every step of this process is painfully slow, taking 5-10 minutes or more to launch and move between most steps in the Setup wizard. In my Task Manager I can see ScenarioEngine.exe thrashing 100% of 1 core during that time.
OK its not a powerful laptop but it is running Windows 7, Office 2013, SQL 2008 R2 OK. All the SQL 2008 R2 services are stopped BTW.
I'm puzzled what that process could be working on e.g. while moving from the Feature Selection step to the Installation Rules step?
And when it hangs it really hangs - I cant even move the window around it is so stuck.
I'm starting Setup.exe as Administrator, from a C: drive folder.
Does anyone know how to avoid this issue?
