What is the best way to use Fritztrainer DVDs/videos on Linux? Is there anyone who is using them on Linux now? Is there any free tool to run Fritztrainer DVDs natively?
Over the years, this question has been asked several times on other forums, but I am not aware of a purely native solution.
According to this discussion on chess.com from 2013, some people have tried Wine, which is "a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OSX, & BSD" (quoted from the Wine website). People have reported varying levels of success, depending on the version of Wine and the distro they were using.
Update: Proton, released by Valve (the developers of Steam) in August 2018, should enable Linux users to run Windows games directly through Steam for Linux. Fritz XIV for Steam and FritzChess 15 for Steam have been available since September 2014 and February 2016, respectively. I don't know whether this also solves the issue of using the Fritztrainer DVDs.
Wine or Virtualbox, as already mentioned, use to be the options when you wish to run Windows programs on Linux. Wine use to be the best option but it can be a challenge and a pain sometimes to make it work properly with the desired windows application. There is a commercial alternative called Crossover which basically is Wine with some more user friendly configuration scripts etc. I don't know how much better than Wine it is but if you are interested there is a free trail you can try out there before bying.
