  So the install batch file was not written to work with this CD, right?
Can you find an install file that *is* intended to work with the CD?

  In general, there's no way to know which of
this is a long name
this is a longer name
was converted to which of
thisis~1
thisis~2
Is there something internal to the CD files that would tell the name (for
instance, are they Ada source files and you could run gnatchop on them)?
Or are there no *~2 files, so the first six characters are unique and you
could manually match the 8.3 names against the names expected by the bat
file?  If so, you could modify the bat file (since you can't change the
names on the CD).
