Trying to re-associate SQL 2005 MDF files to the correct executable file

I was attempting to attach to the Northwind database from SQL 2005 and it gave me some error.
Unfortunately, I pointed it/associated it to a filename called "sqlservr.exe" and now all my MDF File associations are all screwed up.
1. Can someone help me to reassociate it with the correct .exe or service file? For example, the LDF file shows an assocation with "SQL Server Database Transaction Log File (.ldf)"
2. How to successfully connect to the Northwind database from SQL 2005?
With many thanks,
Wally

Aneesh, I attempted to do that initially. Please re-read my first EE Thread above. I accidentally associated a SQL Executable as my file type with MDF. The problem in my first question (#1), is that I need to figure out which Program to associate back to. Obviously it should be SQL Server 2005, but, when I go to re-associate, there is no program list in the Programs list for SQL 2005.

ok, I could attach the database after I updated permissions to the Service Account to have Full permissions. Now I just need to find out how to reassociate with the SQL Server 2005 Database Application.

it is a sql server specific file, you are not supposed to open it, even if you open it, what you are supposed to do with that, it can harm the entire db file

Why are you trying to do this?  This is not MS Access.  SQL Server data files do not need to be associated to any application. Period.
