MTA:SA fix
CC50: Direct3D9 could not initialize
Install Microsoft’s DirectX runtime first. Then check that GTA uses a resolution it can really open.
Could not initialize Direct3D9
Codes on this page: CC50
Steps
Install Microsoft’s older DirectX components
Close MTA and run Microsoft’s DirectX End-User Runtime installer, then try again. CC50 means Direct3D9 failed to start. This step does not show that a part of Windows is damaged.
Choose a standard resolution in GTA
Only if you recently forced a custom resolution or changed screens, or the current resolution is not supported.
Open GTA single player and choose a standard resolution that your screen supports. Exit GTA the normal way before you start MTA.

Update your graphics driver
If it still fails, use the driver support of your laptop maker or graphics card maker for your exact model. Test again after that change. On a laptop that shows an Optimus warning, use the Optimus guide instead.
Careful: Do not use a driver updater program that does not come from the maker of your laptop or graphics card.
