hi,all the packages work fine on win10,nvidia graphics Ti1050-4gb,the only little glitch i had so far on starting Prypiat and Clear skies was a dll error. with Clear skies i had to copy d3dx9_37.dll into the game folder and for Prypiat i had to copy
d3dx9_42.dll into the main game folder.runs with 1920x1080 on mine.looks great.

You could also just have downloaded DirectX 9 from Microsoft.com and installed it. Hopefully your files came from a secure place.
