I copies all my files from XP to a new machine I built: 64 bit, Windows 7 Professional. It had a Asus motherboard which installed SQL 2008 and SQL 2008 R2. (I don't think i can use it for my web project however)
When I installed Visual Studio 2008 Professional edition, it came with 2005 SQL Express.
All was working/is working fine on my old machine.
When I right click on my database which has red x on it, from within Visual studio's left server explorer pane, I get this message:
==============
"The database 'C:\USERS\MyName\DOCUMENTS\MyWebSite\APP_DATA\MyDB.MDF' cannot be opened
because it is version 655. This server supports version 612 and earlier. A downgrade path
is not supported.
An attempt to attach an auto-named database for file C:\Users\MyName\Documents\MyWebSite\App_Data\MyDB.MDF failed.
A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
===============
Since I'm still trying to use SQL Server 2005 express, which is installed, I don't understand why its saying this. I don't understand what is happening.
What should I do?
