Hello I know this might sound unethical, but at the end I will also explain my reasons, plus this is really driving me crazy curious! I have installed a software with a trial period of 15 days, after that time I cannot start it anymore saying the time is over. So I installed it on a virtual machine on the same PC (on VirtualBox) the v. machine was never connected to the internet and after passing the setup file via USB I installed it, but again, it recognised it was already installed and that the trial was over! How can this happen? It cannot check my registry or the files on my real PC and cannot access the web. Plus the installer had been downloaded again (so it's not the same of my first installation, for what it's worth!). How can a software inside a Virtual Machine go outside the machine itself (inception), or whatever is happening here?? If I formatted my PC it should work, so why not on a Virtual Machine then? Thanks for any useful comment! EXPLANATION This software is needed for my thesis, it costs 7000€ and I'm a poor student. The university is applying to buy it but this will take a long time and my deadline is very soon. I'm not willing to steal for anybody, it's just research and no commercial use (and maybe it's even publicity for the software itself!). I'm a part-time developer and I perfectly understand this is not a good thing but at this point probably I will not be able to "trick" the trial anyway, too complicated!
