Question about installation

When i install TP 7.0 the install program only uses 2 out of the 4 disks, it
does not seem to affect TP but i am not certain because i have been battling
the CRT Unit problem on faster computers (doesn't install tpp.tpl which is
needed for update)  if anyone can help please send me an email...
