Hi Przemas, for Linux there is usually a package manager that you use to install Wine. The package manager is usually quite prominent in the main UI, look for something that says "Package manager" or "Install software" or something similar, then run that and inside that there should be a search mechanism and put in Wine in the search box to find it and it will install wine for you.

Once you have installed wine, you can then download the MoI windows version installer and run it from the command line by putting in: wine moi_v3_setup.exe

In order to run windows programs with wine, from the command line you actually run the wine program (so put that first), and pass wine the name of the windows program for it to run.

Once the MoI setup has run there will probably be a shortcut listed on a wine menu for running it.

It's best to do this with MoI v3 which does not need any other kinds of configurations done with it in order to run under Wine. Older versions of Wine need additional things set up like installing Internet Explorer using the "winetricks" program.

Wine is kind of constantly changing and frequently there are small glitches introduced in it, it's not unusual to have some kind of cosmetic font problems for example. Hopefully in the most recent version of Wine some of those may have been tuned up again. If not you may need to run an older version of Wine instead of the most recent version. That's a lot more complex to set up, it involves downloading the Wine source and building it yourself, see here for links on information on that:

The biggest problem with getting things set up is to make sure you've got a good quality video driver. Bad video drivers are very common on Linux, especially for certain types of cards such as ATI/AMD cards. This is probably the biggest weakness of running Linux - if you just try to run it on any random system there is a fair chance that you won't have a good video driver and things related to 3D graphics will not work properly. It can help to do some research and get a video card that you find has been specifically recommended by other Linux users as having a good quality and stable driver. That's a pretty key thing to end up with a stable Linux system.
