Hello guys, "TSZ-Keygen Only" works well, but when you run the software online, it recognizes the key as blacklisted, to prevent it should block that program on the firewall.
Thinking about it made a patch to replace the file "Config.dat" in the installation folder, blocks the registrations links in the hosts and create a rule on the firewall to block software access to internet, so it is just applying the "Patch" , it will be enable the offline activation mode just use the keygen to register , without having problems to be online and block the key!
For those who want to analyze the code just unpack the "exe" with winrar and check the files "Add Hosts.cmd" (made by myself) and "config.dat" (supplied with the own keygen) , opening with notepad
