Not absolutely crazy, I think. I vaguely remember having had this problem once, and maybe not with LabVIEW. However, I think the older installer receives the free disk size modulo 2GB (I32)or 4GB (U32) so you may have to create a file large enough just to get under 32GB or 30GB free space boundary. If I remember correctly, I solved this by duplicating the Windows or other large directory.
Not easy to explain to a customer...Good luck!
