Installing V-One gauge

[Louis8]

I'm a little xthreaded on putting this in, and on this bird i think its almost a must to have. After i download the gauge i see the folder called V-One_Milziv_B737_v2.0..Now what do i do ? do i copy this folder and where do i put it is what i'm not too sure on ,editing the conf. i think i can handle, i just don't want to screw this up then nothing works.

I played around the best oi could to get it in but now when i hit shift 4 a square box and looks like it should be the V gauge shows up black for just a second and goes away.
