Use Apmplanner2 or Qgroundcontrol.
Both are multiplatform, so you can run them on a reliable OS too.

The .Net updates are free from Microsoft. Are you unable to get them?

i update my .net but i still have the same problem and the same error notification

thank you i install apmplanner2 it works
can i replace the autopilot with a similator
