Hi friends I am using HP Pavilion dv7-6135dx laptop and I am facing problem while upgrading the Direct X in my laptop. In my laptop I have windows 7 operating system. When I try to install the Direct X in my laptop at that time I get "a cabinet file necessary for installation cannot be trusted. Please verify the cryptographic services are enabled and the cabinet file certificate is valid."
If anyone has solution regarding this then please help me.
