I just got my copy of SQL Server 2008 R2 Developer edition, and I'm trying to install it. I wasn't able to find any specific instructions after an exhaustive search, although there is information overload on all surrounding issues.
When I insert the cd, it runs for a good deal of time, but never runs. In windows explorer, one file is shown on the cd, "Track09.cda."
Can anyone point me in the right direction?
I'm not sure you have the right CD in your hand. When I pop my SQL2008 R2 Dev Edition CD in and view the contents in Windows Explorer, I see a whole bunch of files including *.MSI, *.EXE, etc. etc.
Back to your question, I would back up your database(s), then uninstall the Express version and do a clean install of the 2008 Dev edition. I've done this several times myself so I know this method will work without any issues.
