**EDIT:** On page 2 I made the mistake of using cmd.exe instead of PowerShell.
'Start-Process' is not recognized as an internal or external command,
operable program or batch file.
...No idea what is up with that. I'm digging around on the internet but I'm stuck at page 2 of your guide:
"open windows Powershell as admin and navigate to the folder you just made, then type:
Start-Process -FilePath "Full path to luvi.exe" -ArgumentList "lit.zip -- make lit.zip lit.exe luvi.exe" -Wait -NoNewWindow
(you will know this worked when you see lit.exe in the folder)"
I don't remember running into this problem before. Also, i'm hesitant to follow the old guide from gamergiving since I remember this process working and the gamergiving guide just has you type a powershell command to download it directly from github:
'https://github.com/luvit/lit/raw/master/get-lit.ps1'
His command installs properly, but I'm guessing the version of lit in your instructions is what made the difference on my desktop.
