    1. Hi, Jim. It is possible to recover your data but the operation is quite complex and difficult to expain through words. Our engineer could offer to help you through remote access by TeamViewer. Let me know if this sounds like a plan to you and we can arrange a time through [email protected]

  4. Hi, i’ve a problem at installation time, when i excecute the installer it throw an error message “The file is corrupted, please try reinstall”. I downloaded the file 4 times, 3 times the online installer and once offline. Can’u help me?

  5. Hello there, I was wondering about a backup feature few weeks ago and looked like something feasible for you guys to include at some point. Any progress with that? Is there any way we can have a step by step tutorial so we can zip and restore machines in the same host or perhaps passing a vm into a new Nox installation if the implementation will take long?

    1. Thanks for following up with us, Nick. As a matter of fact, the backup feature will be released in our next version planned to go live at the end of September. Stay tuned.

      1. Great news, can’t wait. One more thing, I have tried to run the new Gameloft’s Order and Chaos 2 on a clean box with nothing other than google play account on it, once downloaded I start the game and it runs for a while few loading screens and then the game shutdowns, then I try to restart the box and it hangs at 99% loading bar.

  6. I would also suggest to take the whole app portable, and therefore writing all settings and vm within a single folder structure, like portableapps. This could also to make entire backup of app + VMs installed in one go, which gives more backup options.

  7. Hola buenos dias me preguntaba que cuando saldra la actualizacion de NOX 2.4 este es el mejor emulador de android y espera que en la proxima version se arreglen algunos problemas que son pocos por sierto, Si en este emulador se pudiera llamar y enviar SMS de seguro seria un completo exito gracias por responder 😀

    1. Hi, James. Unfortunately I don’t speak Spanish. 🙁 The new version of Nox will probably be released at the end of this month and the phone call plus SMS thing will be considered if there’s strong market demand. Stay tuned.:)

  8. Почему у меня при любой установки всегда выскакивает окно? ” The file is corrupted, Please try a different installation path “
