At build time, the following build error message may occur:
ISDEV : error -7067: Your project contains Setup Prerequisites. These will only work if you choose to have your release contain setup.exe. Please change your release settings to build setup.exe or remove the Setup Prerequisite from your project.
This build error occurs if the release being built is a single MSI package without a setup launcher and a prerequisite file (i.e. Microsoft .NET Framework 3.5 SP1) is included as well. A setup.exe setup launcher is required in order to execute and install prerequisite files.
Modify the release to contain a setup executable:
Modify the release so that it includes a setup launcher, as the launcher is required to call the setup prerequisite code and show any necessary dialogs.
