Hi,

The procedure to generate the RegistrationCode aka RegCode in the version 1.63 with modified date 13.05.2013 is as follows:
Code:
1. Generate 16 radom numbers of base 256=Res1
2. SignedDec(VolumeInfoA("C:\"))=Res2
3. ConcatSeveralStrings("*",Res1,"#")=Res3
4. RC4_Encrypt(Key=Res1,Res3)=Res4
5. Concat(Res1,Res4)=Res5
6. RC4_Encrypt(Key="Lilys", Res5)=Res6
7. byteArrayToBase64(Res6)= RegCode
Hardcoding the drive "C:\" for the VolumeInfo will eg fail on some of my systems, which don't have a partition "C:\". That is just my thoughts.

From my investigation so far, I could not find the RegName and Email(no syntax check) been used or referenced anywhere during the check of the activation key.
They are however mandatory and the user will be promted to fill the corresponding empty field(s) before the RegistrationCode will be generated.

Anyways, the ActivationKey does the same thing but with Key="Tomasz" instead of "Lilys".

It should be noted however that both the initial 16 RadomNumbers(Res1) and the VolumeID (Res2) are in the resulted Regcode and are thus used to generate the ActivationKey, so that the 3 compares it does after decoding and decrypting the ActivationKey will match the original values.

Regards,

PS: If I have time I will try to write a Keygen for it
