HI,

 

MY problem ist that the installation of directx at the end of the pmdg777 installation fails. It says a cabinet file necessary for installation cannot be trusted. Please verify the cryptographic services are enabled and the cabinet file certificate is valid.

 

This ends up in the problem that the 777 does not work. No gauges are installed and no activation window.

 

I had the same problem with the 737NGX but i don't know how i fixed it that time.

 

I seached the internet for the problem and downloaded the dirext webinstaller which gives the same problem. Also the complete installer from JUn2010 gives the same problem.

The cryptographic services are enabled anyway but it doenst work, always the same failure.

 

What is the solution? Did anyone experience the same?

 

Thanks

I am no software or hardware specialist.

 

But I would try updating DX9.

It is one thing that is adviced to do after a new Win install, so I can see how it would hurt anything if you do it now (betterl late than never?)

 

But maybe others have better ideas.

Hi Rob!

 

Thansk for your reply!

 

I've already done it with the webinstaller but i get the same error.

 

I'm using WIN7 64Bit and i wonder why i have to install direct x again since win 7 already has the dx11 onboard.

 

Anyways, i get the same installation error during directx installation, no matter if i download the full executable oder the webinstaller.

 

With this i cannot use the 777 cause when i load it in fsx no activation windows appears and no new gauges are loaded so i jsut see a dark cockpit.

 

Does nobody have the same problem?

 

Thanks

Chris
