You may need this registry fix to run FinalSun:

Red Alert 2/Yuri's Revenge
FinalSun map editor:
http://www.wagnerma.de/yinger/showdownload.php?detail=2
If you only see a black map, FinalAlert 2 YR does not have write access to its program folder. You can fix this by right clicking the "FinalAlert 2 Yuri's Revenge"/"fs101" folder and choosing "Properties". Then switch to the "Security" tab and click on "Edit". Select "User" in the list and grant it full access below. To do this procedure, you will have to enter the administrator password, unless you have disabled UAC.
