Mike,

Under the 1 group, create an upgrade path. Make sure you create an new GUID as the Upgrade Code.

Under the 1 group go to General Information, make sure the Product Version is filled in. Make sure the Upgrade code is the same as in the first step above.

You need to make sure you change the product code and the version when you create a new build. You will probably have to uninstall your application the first time.
