I think i experienced with one of the more recent downloaded installer .exe files, probably for BIAB 2018 WMA only, last december, that it had problems with relocating to the installation folders, when set to install in my case to L:\-BIAB 2018\RealTracks etc. (to a separate internal 2B sata drive for BIAB only); this might have been fixed with later installer versions maybe. Forgot which one alas, and i had to copy the lot by hand from my BIAB USB Audiophile drive; a thing i normally always choose to do with Fastcopy or Teracopy anyway. -F
