DirectX: A cabinet file necessary for installation cannot be trusted.

As I have post on my last article on how to resolve you problem regarding your NBA2k13 if the Xinput1_3.dll is missing I also included there if you have experience problem on how to install you Direct X from microsoft because I also experience such.

In this article I will be writing about my issue regarding direct X and on how I have solved that issue.

Issue/Problem: When I downloaded DirectX file and already installed it and downloaded its content before finishing its installation process I have faced this problem:

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

So regarding that issue that I have solve this by doing these steps:

1. First you need to go \Windows\System32\directx\ or \Windows\SysWow64\directx

if you have Windows 7 x64.

2. Now go to "folder and search options" then (How to go to folder options in Windows 8)

in the "View" tab check "show hidden files and folders" and then "ok"

3. After this the websetup folder will be visible now and then all you have to do is go IN the folder and delete its contents do not delete the folder

4. Then Run "dxwebsetup" again. 

After I suppose and hope that your problem would be fixed!
