The Community Technology Preview (CTP) of Microsoft SQL Server 2005 Everywhere Edition requires Windows XP SP2 or Windows Vista. If Windows 2000 is unsupported I will have to look at other solutions instead for the future. I tried to convert my database from Express's MDF format into Everywhere's SDF format, but ran into problems. With the short time remaining to the version 1.0 deadline (contest submission) the database optimization is something that will have to wait. Now is not the time to introduce more risk in the project.
I also decided to go with the ClickOnce system of deploying the application, which is helping out. It comes especially in handy with the installation of the runtime environments for .NET 2.0 and SQL Server Express. ClickOnce automatically figures out if the user needs to get these installed without me having to write a single line of code/script, which is really neat.
