As a thank you note for providing the app i have an advice for people with Win 11. The issue is that the keygen doesn function properly under this OS. I have a vlinker FS who is recognised as an original part. Instal the app on you PC, get the .txt file with ifprep2. Install a win 7 virtual machine using any virtual manager app, disable virus scan so you can run the keygen, upload the .txt file and the keygenerator on your virtual machine, run the keygen feeding it the .txt and you will get the 7Kb file. Copy it on your machine and that's it.
