Fade In does not run directly on Chrome OS on a Chromebook at the moment. (Chrome OS is essentially an operating system where the Chrome web browser functions as the user interface, and applications run as Chrome apps within that browser interface.)
There are several approaches that can be tried, however:
1. You may be able to run the Linux operating system on your Chromebook. Please see this article.
2. On x86 Chromebooks that run Android apps, it may be possible to use Crossover to run the Windows version of Fade In.
In any case, you can try it out with the free downloadable demo version of Fade In before purchasing.
Note that this information may be outdated. Please ensure you are reading the most up-to-date information available.
1. There is an option called "Project Crostini", which allows running Linux on (some, but an increasing number of) Chromebooks. This has been used by some users to run the Linux version of Fade In. A third-party getting-started guide is here.
2. Some users have also run the Linux version of Fade In on x86 Chromebooks via, for instance, Ubuntu and crouton.Tags: chromebook, linux
