There are two programs you need to download and install before you can add games to your Zune.Note: If you updated your Zune from 2.5 to 3.0 you will need to uninstall Microsoft XNA Game Studio CTP.
The first program is Microsoft XNA Game Studio 3.0
. Download it for free here:http://www.microsoft.com/downloads/details.aspx?FamilyId=7D70D6ED-1EDD-4852-9883-9A33C0AD8FEE&displaylang=en
The other is Visual C# 2008 Express Edition
. Download it here:http://www.microsoft.com/express/vcsharp/Default.aspx
Install Visual C# 2008 Express Edition
first (vcssetup.exe), then install Microsoft XNA Game Studio 3.0
XNA Game Studio 3.0 is a toolset intended for developing games on the Zune, Windows Computers and Xbox 360. Since we are not developing games (just syncing them to the Zune) we won't use it but it still needs to be installed for any of this to work.
