Handle error when Origin install not found on Windows

[GeckoEidechse]

When on a Windows machine where Titanfall2 is NOT installed with either Steam or Origin, the check for Titanfall2 Origin install fails and causes a panic.

called `Result::unwrap()` on an `Err` value: Powershell(Output { inner: Output { status: ExitStatus(ExitStatus(1)), stdout: "", stderr: "Get-ItemProperty : Cannot find path 'HKEY_LOCAL_MACHINE\SOFTWARE\Respawn\Titanfall2\' because it does not exist.

This registry key is only set by Origin installs?
