Well, I don't use windows, but I can try to diagnose your problem

I'm not sure exactly about your description you showed above...
I have a feeling since you got some output as ''undefined'', and also ''ENOENT" (which means Error No Entry), meaning: No directory entry
This would mean you are not launching the heatledger server properly...wrong directory perhaps,
To me this looks strange: "C:\\Users\\j-digop\\AppData\\Local\\Heatwallet\\app-1.0.1\\resources\\heatledger"
Since the heatledger server is located in a folder which you unzip from github, it should not be looking for it in ''AppData\Local\app-1.0.1\resources\heatledger"
This is just my feeling for now...
I use linux and not the gui server, but I think something doesn't look right with the way you are launching it.

The windows install puts it in the AppData\Local directory if I remember correctly. I've installed it on both windows and Linux, but haven't done the windows one in awhile.
