For F1 2018, for ppl having some troubles.
Go into "History", take the 1.06 version, extract it NOT on Desktop.
Open with admin rights. Change drivers names. (You can also edit them through config file.)
If you wanna resize it, open config file with Notepad, go to the end of the file, you should find 4x <string>1</string>, you can edit it there but remember to use "," and not "." for décimals.
Ex : <string>0,7</string>
<string>0,7</string>
<string>0,7</string>
<string>0,7</string>
Hope you'll enjoy.
