It is no longer necessary to change your decimal separator and date format if you use non UK formatting since the game is now fixed to the UK settings.

==== Instructions for older versions ====

There are two common issues with Aurora installation that cause headaches for many players, especially in continental Europe. Basically, if you're not in blue on [https://upload.wikimedia.org/wikipedia/commons/thumb/a/a8/DecimalSeparator.svg/1920px-DecimalSeparator.svg.png this map], these issues will likely affect you. 

The code of Aurora depends heavily on the number format you use for your computer. Steve's from the British Isles, and uses normal British numbering formats (e.g., 9,876,543.21 is just under ten million). This is baked deeply into the game's code for handling all kinds of numbers, and this code will break with different number formats. If you have a different number format on your computer, Aurora will be virtually unplayable, since numbers will get multiplied or divided by several orders of magnitude in all kinds of weird places. 

Similarly, the date format for "long date" should be set to "dd MMMM yyyy". This is less important, as it's mostly a display issue (the default format in some places adds the day of the week, which makes the date too long to see in certain windows). 

These are known issues. As such, if you want to play Aurora, you need to make sure you're taking care of these issues.
