Simulator Crashes on launch (Windows 8.1 and 10) (read ECONNRESET)

[Evangion]

Today I downloaded the simulator on two separate machines and I am getting the same error on each. The following is the output from running it from the command line in my most recent attempt. Any help would be appreciated.

I have no idea if the installer requires admin rights but you may try this:
Are you running the installation from an Administrator account?
Have you tried to run the installer (Fitbit OS Simulator-latest-0.6.1.exe) as Administrator?

[JonFitbit]

The installer does not require admin permission, this seems to be networking related.

Please make sure that nothing is bound to TCP ports 63981 and 63982 on your machines and that your firewall isn't interfering.

[Evangion]

Testing at home my firewall is completely disabled, Just in case I added this executable to the list of programs allowed through.

1. I checked netstat -an and see nothing on the ports you specified.
2. I start the simulator. 
3. Once I see the GUI come up I run netstat -an, and I see both ports show listening. 
4. Wait a few seconds, and the app crashes showing what I previously posted. 

Just in case, before testing this I did uninstall then re-install with admin privileges.
