The installer looked for retroarch.exe in C:\RetroArch-Win64 and Program Files\RetroArch only, so a RetroArch under Program Files\ RetroArch-Win64, in a Steam library on another drive, or in an installed ES-DE's Emulators folder went undetected. All three are searched; Steam libraries come from Steam's own library list.
