PHP port of xp_activate32.exe
This is a full PHP port of xp_activate32.exe. Ported line by line. But why? - because why not! And to be honest, I don't understand any of the calculations, code was made in a way to replicate the original code workings in 1:1.
Since it's a "1:1 port", before submitting a issue with an installation id that doesn't work, check if it works in the original xp_activate32.exe. If it doesn't work in this port, but works with xp_activate.exe - then go ahead.
