When we try to install \ run a setup MSI file created using Visual Studio 2003 , in a machine having higher version of .net framework , it will not allow to install the product and throws an exception as follows.

“This setup requires the .NET framework 1.1.4322.Please install the .NET Framework and run this setup again.The .NET framework can be obtained from the web.
Would you like to do this now ? ”
To resolve this issue follow these steps.

1. Open the setup project and go to the launch conditions.

2. Check the properties of the .NET framework launch condition.

3. In the supported runtimes [1.1.4322] is already added by default. We need to add other versions of the supported framework using a semicolon delimited string.

4. Use 1.1.4322;2.0.50727 for installing the MSI file with .net framework 2.0 , similarly 3.5.21022 and 4.0.30128 for 3.5 and 4.0 version.

So now the MSI file will run , in higher versions of .net framework , even if originally built with .net framework 1.1
