windows: won't work with programs in \Program Files

[mikob]

Not an issue with your library per-se. Writing here for posterity and documentation purposes. There is a permission error if your go binary is installed in program files in windows with the default permissions:

Error updating: rename C:\Program Files\LipSurf\LipSurf Companion App\lipsurf-companion-app.exe C:\Program Files\LipSurf\LipSurf Companion App\lipsurf-companion-app.exe.old: Access is denied.

Might be worth documenting what permissions are needed by each OS.
