I installed COD 4 on my PC but when the installation finished it said this :

DirectX(R) encountered an unrecoverable error.Please check the DirectX(R) FAQ for possible solutions.

I downloaded the DirectX 9 and saw this :

A cabinet file necessary for installation cannot be trusted. Please verify the Cryptographic Services are enabled and the cabinet file certificate is valid.

How can I fix this problem?

In order to fix this problem, you can try several things. Go to Start -> Control Panel -> Administrative Tools -> double-click Services -> right-click Cryptographic Services -> click Properties -> choose Automatic for Startup type, and then click Start.

If this doesn't work, update your DirectX to the latest version. Also, you need to update your video card driver to the latest version then uninstall and install the COD game again.
