I am trying Home Assistant for the first time on Windows 10 and I am unable to start the application. I followed the instructions on the wiki. I am trying to run version 0.79.0.

Any idea what is going on?

Try to use hass.exe

[jia175891641]

me too ,use hass.exe like useless my os is win8.1 .verson0.78 was run no problem

[awarecan]

I don't have problem with dev branch. Python 3.6.3, venv, Windows 10

[martingagne]

Same issue with hass.exe.

[awarecan]

subprocess is not supported in Windows by default, see https://stackoverflow.com/a/44639711/6131995

However, we had set our event loop to ProtractorEventLoop in #16737, I am not sure why it is not working.

BTW, that code only be executed if you are not using venv, so the workaround could be installing venv. See https://docs.python.org/3.5/library/venv.html

Same problem here after upgrading to 0.79.x (on a Windows 10 x64 system - Python 3.7). Went back to 0.78.1 and evertything is working fine again.

Thanks

[emilyplusplus]

I have this issues even when using venv

[awarecan]

@emilyplusplus could you provide the error log?

[awarecan]

Please help me test the fix in PR #17061

[kano79]

Installed the new version 0.79.3 with the fix and its working fine again. Thanks

[RealGandy]

Same here. 0.79.3 runs fine on Win 10.
