Oh

and for those who do want to make totally sure ..

https://www.cybrary.it/0p3n/advanced-exe-multi-protection-reverse-engineering-free-tools/

shows you how to modify the UPX compressor so that someone with the source
code (it's open source) will have difficulty.

I don't use it - my copy protection is my support and a base64encode name
of company string - it is breakable but I don't care
when something goes wrong - and it will especially if windows is involved -
they will have to come to me  or start again.

If somebody "cracks" it and it gets spread so what I wouldn't have had them
as clients in the first place.
In the old apple 2 days I bought an assembler called Lisa ($139.95) on a
copy protected disk.
I had a disk copier that could copy the disk but the new disk would still
be copy protected so I was up
till 4 in the morning with my copy of "Beneath Apple Dos" going through 3
levels of protection from the unprotected Boot Loader
to other bits of code that was Xored before executing and then I got to a
bit of text ... For $139.95 you can go to sleep tonight.
I Laughed and went to bed.

Most crackers do it for pedagogical reason and our systems aren't on their
Radar so why put hoops in the way of the honest people.

btw for anyone who remembers those Halcyon days I also bought (not copied)
Randall Hydes Anix system (love the name) which was a "Unix Like" OS for
the Apple 2
which had 48K Ram and 143K on a floppy disk WT?~#@!
