In this update we have :
1. internal code virtualization & obfuscation
2. complex arithmetic calculations

What you have to do:

Quote

1.Reverse it.
2.Find Key Generation algorithm 
3.Write your keygen 
4.Maybe write some detail about what you have done

I hope peoples who interested in Reverse Engineering learns something from this type of challenges.

Best Regards.

Very strange,something like self-modifying code,hard to follow

I cannot even see where wrong key gets displayed,very unique and strong

Nothing really strange,the so called "self-modifying code" is actually his obfuscator. In which spot did you stop?
