I am looking for a "simple" technique.
The users of my particular application will not go to the extend of
decompiling the application.
They are more likely to make unauthorised copies of the software to run on
more than one machine.
Each time they install our software at a site, I want the install program to
display a code that is unique to that machine in some way.
The customer then contacts us and we give them a key to type in that allows
the application to be installed and run.
If I knew some useful data locations on the PC or in the registry that I can
read and use to create this lock code then I could sum the value of these
parameters, add the date and xor to provide a code.
Thanks

whichever technique is ineffective if the program can be decompiled !
try my Goliath.NET obfuscator (pre-release version):

news:Of***************@tk2msftngp13.phx.gbl...I would like to set up a copy protection scheme where the application
must be provided
with an unlock code before it can be installed.
Any ideas for a relatively simply system for doing this ? I seem to
remember
something like reading PC BIOS, adding the current date and XORING with
a fudge factor to create a code that the user rings up and quotes. In
return we give then an unlock code.
(I have also forgotten how to read BIOS).
Thanks for any help
Regards
David
