Halo: Combat Evolved - Library Suite (Game Installation Loop) [Extended]

This looped part of Library Suite can be heard during the installation sequence for the game, when the progress bar shows up (after setting up the game's folder and such).
The xNVSE discord server helped me find the audio files for this song and other songs/sounds that are present in the installer, which are inside SetupENU.dll.
File name: SFX_AUTORUN2.WAV

This track is a very short modified version of the Library Suite's Second Segment, referred to informally by fans as Library Thick Ambience, or the Library First Floor Hallways.
