Subprocess Startup Error

[xlargedinosaur at aol.com]

Does anyone have advice on how to resolve this message when I attempt to open IDLE? 


"IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection."


I am running Windows 10 Home on a 64bit machine.


I am running Python 3.5.2.  


I have tried uninstalling the software and reinstalling but no luck with that.
