No logging during Windows Launcher portion of install / text mode installer window closes immediately on error

Currently there is no logging to text file during the Windows Launcher portion of the installer, this can make it hard to debug issues with installer startup.

Specifically for the text-mode/recovery installer, if there is an error while running the launcher (for example, a severe python error or a file missing), the text window will just close immediately, which again makes it hard to debug issues.

I have partially fixed this issue in 6461a12 - the fallback install launcher previously would just exit once the python script exited. It will now pause on exit so you can at least read the error messages if something went wrong.
