Installing F# for Silverlight 4 runtime in VS2010 with SP1

In case you need the F# Runtime for Silverlight 4 after VS2010 SP1 is installed I recommend the following procedure:

1. Download the Microsoft Silverlight 4 Tools for Visual Studio 2010

2. Don’t execute the installer (these tools are already installed by the VS2010 SP1 – but not all of them – see Description of Visual Studio 2010 Service Pack 1 and Microsoft Silverlight 4 Tools for Visual Studio 2010 and compare the differences)

3. Extract the files from the installer and look for the file FSharpRuntimeSL4.msi

4. Install the FSharpRuntimeSL4.msi

To validate the installation you can check if the C:\Program Files (x86)\Microsoft F#\Silverlight\Libraries\Client\v4.0 folder was created or see the you have the Microsoft F# Runtime for Silverlight 4 version 2.0.0.0 on the list of programs installed.

I’m posting this more has a remainder for me, but it can be useful for those who have the same problem.
