I'm running sql server 2008 R2 Developer on a win7 (pro) workstation. I would like to keep this installation because it has SSRS and Analysis Server. But I was not able to attach a sql 2012 DB so I downloaded Sql Server Express 2012 (per the picture below - 1st option selected) and installed it. Sql Server Express 2012 appears to be running -- per my services list, but I cannot see the instance in ssms 2008 R2. Do I need to uninstall Sql Server Express 2012 and then download another option (from the picture below)? How should I proceed so that I can have a working/workable instance of Sql Server Express 2012 that I can see in ssms (whatever required version) and also keep sql server 2008 R2? which download should I select (from the picture below?
