OK this isn't funny anymore.

I freed up 50G of space on my e: drive (hard disk drive).
Overkill, I know.
I copied over my f:\bb files (hard disk drive) to e:\bb

I attempted to install once again.

I chose a minimalist install.
Just BIAB, no Realband.
Just Pro Real Combo 1, 2
Just Mega Real Combo 1, 2

So what does BIAB do?
It attempts to install Pro Real Combo 1, 2, 3, 4
Mega Real Combo 1, 2, 3, 4

It aborts each one in succession.
Total failure of installation.

I did better a couple of days ago trying to install to f: that had 6 G. frown
