Leo,
you can always the idiotic Lotus method of the past. WHere the
instalaltion floppy was self modifying (repalce that with exe) and
could only be used once to install. If you wanted to move it to a
new pc, you uninstalled it which fixed the floppy and then re-
installed it.
The problem was, we had a disk crash and Lotus refused to replace the
floppy. Which was the last Lotus s/w the company ever used.
