(the "full" installer, not "little 15mb" one)

if so, suggest alternative course of action:
1. usb flashdrive 16gb or larger
2. download 1 of following (all free use):
- boot buddy
- install disk creator
- diskmaker x
3. use 1 of above create bootable usb flashdrive installer.
4. boot flashdrive installer, , try again.

note: before attempt create installer, make backup copy of high sierra installer app -somewhere else- ... archive drive, etc.
know idc above delete installer app applications folder after has created bootable flashdrive.
want "archival copy" stored somewhere, don't have download on again!
