Client setup - SQL server selection

I'm working with my first B1 client that is using SQL 2005.

In the B1 client on the choose company window there is a choice for Current Server.

On the client that is installed on the server I have a choice for MSSQL and MSSQL_2005. On all the client installs I only have the first choice. Should it not give me the option for both? How do I get both options to show?

Thanks
