Yes but for me there is probably a problem of registry on my windows 7 machine.
However i tried to run Flightgear on a Vista machine.
Updates were up to date : green flag
and
VC redist x64 2015 (very last version upadte 3) is installed with succes !
And i said to myself : GREAT !
And you know what (after a long installation of flightgear on that old machine) i run the Flightgear and i have the same type of error : the name is just different MSVCR100.DLL is missing....
