You need to provide some more info my friend . 

What 

With

When

Where 

Why

. Is this something your experiencing trying to install the game? or do you have it installed already but this is on first launch?  also what OS build do you use? as well as hardware configuration? and installation directory?  Do you by any chance get more information provided with this error message, Windows will normally provide an info box with error code, or just a simple pop up.
