installing v6

After campaigning vigorously for a couple of years I finally got
management to accept the idea of giving WDSCI to all the programmers.
The install was a nightmare.  It was impossible to install from the cds,
even in safe mode.  It was impossible to install from disc images in the
IFS.  It was impossible to install from disc images on the local hard
drive. The only thing that worked was disc images on a portable USB hard
drive.  Needless to say it didn't make a very good impression on anyone.
It was about 3 months ago and I can't remember the specific error--just
like an end user <g>--but it failed with the same one for everybody in
each of the modes that didn't work.  

Any suggestions on avoiding this?  I know it may not be enough
information to solve the problem.
