How do i fix 0xc000007b error

When i launch some programs i get this error i am using windows 7 32-bit it is a fresh install. Just with updates does any one know what i could do. I don't want to buy any software so a free way would be appreciated. I have tried looking on Google but i didn't find any thing. This is the error i got. Thanks in advance.

EDIT: When i say some i mean programs in general i dont want a fix for just one of them.

Google is your friend, use it. Googling TestOpenCV and c000007b results in this link http://msoos.wordpress.com/2010/09/11/0xc000007b-error-solution/

My answer is entirely the result of the google search.

The Problem

0xc000007b error comes mainly from mixing up 32bit environment with 64bit one, that is you have an 32bit application that tries to load a 64bit dll.

I used a free portable program to do this: "Dependency Walker". After you download it you can open any PE file (exe, dll, …)
