It looks like Windows 10 isn't shipped with some of the components TUG needs (and the Windows 10 upgrade actually seems to remove one of them). We've bundled these in the most recent version of TUG, so anyone installing the game should be fine, but if you are running an older version of TUG and you do not want to get the latest update, you can also manually (re-)install the following items, which can be downloaded directly from the Microsoft site:


Visual C++ 2012 Redistributable
DirectX June 2010

After installing these two items, TUG should have everything it needs to be able to run in Windows 10.
