A file with a cpp extension is for the programming language "C Plus Plus", which insinuates it is part of a Windows DirectX or DirectPlay dll (Dynamic Linked Library) file, such as would be found in a "Microsoft Visual C++ xxxx Redistributable" file from a Windows Update, with the "xxxx" representing a year of release, such as 2008. Do you happen to have DirectX v9.0c installed on your computers?
