SQL Server by default does not install under an instance name. I believe you can force them to install under a specific instance name to differentiate the two versions - check the install documentation as it has this information.

I've done it (SQL 2000 + 2005 beta and 2K + 2005) and had not problems at all. Just remember to install different instances. -- LuisR Luis Alonso Ramos Intelectix - Chihuahua, Mexico Not much here: My CP Blog!

You should create a registry key. If you're using fw 1.1 you can use the OpenNetCF Library to do this. Creating a file extension association should then be the same like doing it for windows. Ingo

Yes I know that it's there. But if you use the constructor there should be no problem. If there is a problem they way you tried, it sounds a little bit like a bug to me. So I would try something different. :) Ingo
