The history of AntiDuplicate starts from 2006, and it has never been cracked, and there are no cases of correct copying of AntiDuplicate drives.
All search results about AntiDuplicate crack, serial, and keygen are fake.
By the way, we never used any keys or serials.
AntiDuplicate DLLs contain a powerful anti-modifications and anti-debugger mechanism. All critical procedures are virtualized.
Function's parameters are randomized for every function call.
Each AntiDuplicate DLL and the corresponding function's protection algorithm, parameters, and code samples are unique and exclusive.
Therefore, even assuming that one of AntiDuplicate DLLs will be cracked, all another AntiDuplicate customer's kits will still be reliably protected.
