### Environment
* Elixir & Erlang/OTP versions (elixir --version):
* E…lixir does not run, but Elixir 1.10.3 was selected to be installed.
* The Erlang version, as reported by the installer is 9.2.
* Operating system: Windows 10, version 1909, OS build 18363.900
### Current behavior
The Windows installer found [here](https://elixir-lang.org/install.html#windows) does not properly install Elixir. The installer reports no errors, but after installation, both iex.bat and elixir.bat fail by crashing. The application werl.exe fails similarly but then automatically closes without the user being able to inspect the crash.
When running `iex.bat` in Windows Terminal with PowerShell, I get:
```

### Expected behavior
The expectation is that the installer should just work. The crash message seems to imply a version mismatch with Erlang, but the installer should properly install both Erlang and Elixir with the correct versions.
