UNPROTECT FOR LOTUS 123 RELEASE 3

The Lotus Release 3 install disk is copy protected until you enter your
name and your company name in a registration screen.  There is NO WAY to
update this registration information even if you have the original disks.
This patch will allow you to create a working copy of the install disk
that does not contain this information.

Make the patches on the installed copy on your hard disk.

First, zap the registration info contained in the file "INSTEXT.RI":

Now the names are out of the title screen but the program won't run!

-----------------------------------------------------------------------------

It's a good idea to try running 123 and INSTALL from your hard disk at this
point.  They should work the same as before except 123 will display the
opening screen without your name in it.

To make a working install floppy:
-Make a copy of the original install disk.  If you use DISKCOPY you'll get
 an error on the last track.  Ignore the error.
-Copy the files "INSTEXT.RI", "123.EXE", and "INSTALL.EXE" from your hard
 disk to your copy of the install disk.
-ERASE "123.E!E" from your copy of the install disk.  (The install program
 doesn't care if 123.EXE isn't compressed.)

That's it!  Now you have a "clean" install floppy for Lotus Release 3.  The
remaining diskettes aren't copy protected.


NOTES:

It would be better to allow entering any information whatsoever in the
registration screen rather than zapping it entirely.  I decided not to
bother with this because I expect Lotus will come out with a new release
soon to fix bugs, which will require a new unprotect anyway.

Removing the key disk checking from an uninstalled original would be a
more logical approach to fixing the 123R3 protection, but my copy is a
"hand me down" from a user who switched to another spreadsheet.  I had
no uninstalled original to work with.

This is the first instance of copy protection on high density disks
that I have seen.  Let's hope Lotus isn't starting a bad precedent!
