Extracting file from MSI package

[sendersu]

Well, that dll is not the point you should pay your time for....
why? because it does not have the full s/n validator as the java classes have.....

it accepts even fake s/n, here is an example:
00000-99999-00000-00000-00000-0000z

again, the real s/n validator is hidden deep deep down in a highly obfuscated java code (yes, not names, but java code!)
you'll have a real fun reversing it, I guarantee it to you

if you are interestd, I could post the validation code for S/N from that tricky dll.....
