安装程序与 2010 64 位更改平台

Question

I created a setup installer in vs 2010 and it is in .net Platform 3.0. Because my app is 64 bit, I also made the setup installer x64 (solution explorer-> target platform). it compiled and build fine. when I am ready to use it, I copied this installer file to another box and run it. It complains that I need .net platform 4.0. How is it possible? How to changed it back to 3.0? How to fix this?

Sometimes Visual Studio setup automatically adds a .NET Framework launch condition to the package. So you can try this:

• select your setup project in Solution Explorer
• click "Launch Conditions Editor" button in Solution Explorer top pane
• modify or remove the .NET Framework launch condition
