minor Installing

I am having a Hell of a time installing this, i have everything i need including a fresh install and the .exe for freelancer, but in FLMM i cannot select the exe as the directory there for i am unable to activate the mod. I even did a test run on the freelancer.exe and it ran afterwards making a fresh install to try again. It never shows up as a exe when looking for a directory. I have been looking around to see if anyone else had any issues like me but i seemed to be the only one posting about it. Please Help.
