Steps to reproduce

1. Use environment variable in a Julia path in settings of julia-client, e.g. %HOMEPATH%\AppData\Local\Julia-1.3.0\bin\julia.exe

2. Julia REPL crashes, showing:

Press Enter to start Julia. 
Start-Process : This command cannot be run due to the error: The system cannot find the file

   Command

I want to use env vars here, because I use sync-settings to synchronize settings between two PCs which have Julia installed in different directories, but same directory relatively to the %HOMEPATH% variable.

Just use ~ instead of %HOMEPATH% (which looks up USERPROFILE). I don't think supporting arbitrary env variables makes any sense here.

And does the ~ work on windows? Because usually windows does not support ~ for home directory.

[pfitzseb]

It does, yes. We're internally resolving that to %USERPROFILE%.
