how do i get his working, the install in the folder is a windows batch file which then opens command prompt which then promptly closes, ive looked at both the 64 bit and 32 bit but have the same result,  please help

This is a programming library that you include in your own programs in order to create retro-style graphics. The installer just copies the library in suitable target folders. Next step is build and run the examples in /samples folder, and then write your own games using it

so this is more or less just a visual program to overlay the game?

No, this is a programming library you use to implement realtime 2D retro graphics. You need to be a programmer to use it:
