Bear in mind if you are running on a resolution which is under the minimum resolution of Football Manager 2017 you are not officially supported and the game was not tested under these conditions.
For example, if you are using a Netbook, the minimum resolution requirements for FM2017 (1024 x 768) will not be met, as the screen resolution of your computer is 1024 x 600.
You can boot the game (avoiding the 'game is already running message') by following these steps:
- Open Steam and access your Games Library
- Right-click on Football Manager 2017 -> Properties -> General -> Set Launch Options
- Type this in the box: -small_screen -windowed
- Click on OK, close the window and launch FM17 through Steam
Typically Netbooks offer fewer features compared with Notebooks and Desktop computers; for example, less processing power and reduced ability to run resource-intensive operating systems. Based upon this, you will need to refer to the System Manufacturer to confirm that your computer is designed for resource-intensive games such as Football Manager 2017. SEGA and SI do not offer support for this game on Netbooks.
