I've been trying to update my version of DirectX from 9.0b to 9.0c.
Everytime I open the setup it instantly fails the install showing a message
saying, "A cabinet file necessary for installation cannot be trusted." I
thought maybe it had to do with my video and/or sound card drivers thinking
that they might not be WHQL certified. So I updated those drivers and
verified their certified signatures in the DirectX Diagnostics. Yet once
again, I tried installing DirectX and it still comes up with the same error
window. At this point I have no idea what it could be. I'm using Windows XP
Service Pack 1 and I know that Service Pack 2 already has the newest version
of DirectX. Unfortunately I'm having seperate problems installing SP2 also.
Any thoughts?

Go here and download DirectX Eradicator. Remove the old DirectX first
then try installing 9.0c.

I get the same message and this "Please verify the Cryptographic Services are
enabled and the cabinet file certificate is valid". The Cryptographic
Services are enabled. I have SP2 and DirectX 9.0C installed. I was trying
to install the December 2005 updates to DirectX.

If you are getting the Cyrptographic Error, then do Run> net stop
cryptsvc; ren c:\System32\Catroot2 oldcatroot2; net start cryptsvc.

I tried this, still got an error message and ran System Restore.

Here's the original error message: A cabinet file necessary for
installation cannot be trusted. Please verify the Cryptographic Services are
enabled and the cabinet file certificate is valid.
