Fails to compile P3Dv4

I have just installed ADE v1.75 and upgreaded to v1.76.
Now when I go to compile it tell me that it is unable to compile as it cannot find the correct file folders to enable it to compile the bgl.
My guess is that i need to point the Bglcomp and Shp2vec folders to the correct place, but no matter where I pointb these folders in setup options I continue to be unable to compile.
Can some kind soul please tell me where these folders should be pointing.
Oh and the SDK for P3Dv4 is installed.
