Hi,
First of all I installed the 2008 AdventureWorks Database Refresh 3 Samples and everything seemed to install fine. However the database did not exist within my local SQLExpress instance, so I looked at the prerequisites and realised I was missing most of them (installer really should have failed but oh well).
I then upgraded my local SQLExpress instance to 2008 with Advanced Services. I installed Full-Text Search and also enabled FILESTREAM.
Then I removed the installation of 2008 AdventureWorks Database Refresh 3 Samples since it wont let me repair or upgrade and tried to start again. Now when I install, after I select the features and it asks which local instance to use I select "SQLEXPRESS (engine)" and it wont let me click Next.
Why wont it let me click Next?
