Thanks for the feedback. I’m not sure there is an easy solution to this. I know some people managed to run FS under Linux using Mono.
In general, FS in its current state is only intended to run under Windows. This is also the only environment we’ll be able to test new version with, at least for now. For the future, we have plans to create a version that can run on Linux or Mac OS X machines, but we have some other features we’d like to implement first.
Maybe running Windows in a virtual machine under Linux would be an option for you?
