Crashes immediately after launch(STEAM) \"Program Xrengine.exe not running\" (S.T.A.L.K.E.R.: Clear Sky)

(WINDOWS 10!!!)

I read somewhere that it is necessary to uninstall the update KB2670838, but I have it in the list.

The flight log is empty

(The log remains empty)

Total I have 2 problems, please help...
