Fucked up fact of the day: UltraISO stores a table of the first 6 bytes of md5('UTRISO' + reg. name + reg. key) of all licenses it deems valid, instead of a denylist it's effectively a license allowlist... a very interesting way to combat license leaks, I'll give you that.

This raises a lot of questions, does everyone who buys UltraISO get a personalized setup file along with their purchase? The program doesn't get updated all that often. Is there any way to use an older version with a recently bought license? Who approved this?

Wow. Maybe it's not a primary mechanism? How many licenses are there?

55,507 in 9.6.6
65,450 in 9.7.6
The only thing that seems to satisfy the internal variables for acting as registered is the MD5 match routine
