Mavproxy does not run - CLI opens for a second then closes

I cannot get MAVProxy to run on my Windows 10 machine. Installed fine, but the CLI window only opens for a quick second then closes and nothing else happens after that. The example .bat files run ok and the CLI stays open.

Can anyone help me get mavproxy running?

Are you running the mavproxy.py or compiled mavproxy.exe?

I figured it out.

I am running the compiled. Exe.

I looked at the bat files and figured out I needed to specify my com port. So I got it to run fine with the command
mavproxy.exe --master=com14

Hello, I am having the same problem, where exactly do I type this command?
