Thanks Konrad I believe the mac address will suffice. In addition I will probably some other hardware related data and create a hash from it. I emagined there would be a solution for this problem but it semes its not that easy.

You can get MAC addresses via QNetworkInterface::allInterfaces(). Some encouragement: 99.9% of all PCs and Laptops do have a network card and/or Wireless Interface. Unless you target the 0.1% of non-networked machines you can assume to have one (even if it is unconfigured). At the very least if your app has network access then you can assume ethernet (modem-only machines are exceedingly rare these days). Some words of caution: MAC addresses can be changed in software. Depending on your paranoia level you may not want to rely on them - in that case you may want to think about hardware dongles to secure your app. Konrad Diese E-Mail und ihre Anhänge enthalten vertrauliche und/oder rechtlich geschützte Informationen.
