I have simplified things a bit to help understand the problem.. My 32bit target machine does not have .NET Framework 2.0. I have a project on my developement machine including a solution with both a Windows Application and a Setup Project. I have chosen one prerequisite: .NET Framework 2.0. After building the application and moving the .msi to the target machine, I'm confronted with the following message when I try to run the install.. "This setup requires the .NET Framework version 2.0.50727". Please install it and run the setup again etc.. I'm aware its not there which is why it's included as a prerequites installation. Any thoughts on what needs changed? If I run the NetFx20SP2_x86.exe thats included it installs fine.
