If I understood everything correctly I tried each command line argument in that python file.  I believe windows can't find the file each time but I'm attaching this log to be sure.  I had to trim it by A LOT because pastebin woulld't let me add the whole thing.  Here it is.  https://pastebin.com/TcWYqN5p 

I have been looking at the Kodi Steam Launcher addon. You can create a Standalone Launcher to launch a game in Steam like this:

Code:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<advanced_emulator_launcher_configuration>
<launcher>
<name>Steam game title</name>
<category>Steam</category>
<Launcher_NFO>Steam game title.nfo</Launcher_NFO>
<application>C:/Program Files/Steam/Steam.exe</application>
<args>steam://rungameid/steam_id</args>
</launcher>
</advanced_emulator_launcher_configuration>

For each game you need to change the steam_id. The NFO file with the metadata is optional as so is the category. Also, make sure the path to Steam.exe is the correct one (I don't use Steam and have never installed it). Please tell me if this works.

Proper support for Steam is planned for AEL 0.10.0. In the mean time you can create standalone launchers for every Steam game or use the Kodi Steam Launcher addon.  

This looks like it did trick but I do have some questions.  I'm still getting familiar with AEL but I knew enough to fill in the XML data via the AEL menu in Kodi.  If I were to create this file from something like notepad, where would I put the launcher file? 

Under utilities you can import a launcher into AEL. Here is an example that I use for retroarch
