Unable to start SITL

Hello,

I am trying to start the SITL for multirotors on mission planner version 1.3.74, but i can’t seem to do so and this message pops up every time i try.

May i know how to resolve this?

Thanks!

It’s working only on beta version of MP. So update to beta mission planner and try.

Ok thanks!

May i know how i can upgrade it to the beta version?

Go to help page on the MP and beta update.

Got it, thanks for your help!
