THX so much for this amazing work to unlock this game. You are so great kimsama.
Maybe for those who didn´t get run the game. First it did not work, even thoug I installed Direkt X and the Visual C++ and open the start.bat. The error has been deleted after I delete the complete TC5 folder, start the PC again and unpack the zip file again (not to open the 7zip programm first, just via right mouse click and extract). After that everything works perfect! Greetings from Germany.
