Hi all,  
I am trying to install the helloWorld app to a mangOH red board using the legato developer studio (in Windows). However I am getting a framework compatibility error when I try to download the app to the target. How do I update my legato framework version to match the target (I have downloaded the latest developer studio version there is).

Thanks

Hi @bbrds

This has been explained in this post: [https://forum.legato.io/t/adding-newest-version-legato-framework-into-developer-studio/2654](https://forum.legato.io/t/adding-newest-version-legato-framework-into-developer-studio/2654)

Unfortunately, building a new Legato on Windows is not supported at the moment.
