Ground control opens to blank screen


Hi all,

Totally new user here. When I try to double click “Launch Ground Control.bat”, all I get is a black screen with a white rectangle in the middle.

The cmd window shows the following:

I’m running Windows10. Any idea what I can do to get it to load? Any additional information I can provide?

Edit: I do have python 3.3.5 installed on this laptop. Is there any chance that’s causing an incompatibility?

I haven’t heard of that before, but it is a possibility. I have had python do a lot of strange things in the past with different version, but it looks like it is loading with 2.7 from the log. I’m a little stumped, I haven’t seen anything like that before. If you feel comfortable trying I would recommend the “run from the source” approach which might give us more information about what is doing on

I uninstalled my other Python versions to see if that would solve the issue, but no change.

I can try to install Python 2.7, kivy and the other dependencies tonight and see what running from source code does.
