I took a copy of mdf and ldf files from SQL Express 2008 instance. SQL Service was in stopped mode. Now I'm trying to attach them to SQL Server 2008 Enterprise Instance. I get error message: database cannot be upgraded because it is read-only or has read-only files.
I have checked file properties and there is not read only checkbox checked. How I should go forward to get these DBs to be attached. I dont have access to this 2008 Express instance anymore (it's in different city and I should make this change during weekend).
Any help is appreciated
