Hello nasss, as i can see this is your very first post, you are welcome to TechDiscussion.
As far as your query is concerned, you dint mentioned if you are playing the game on Steam or on local PC? Anyways, If you are playing it on Steam then it should be at the following location:
C:\Program Files (x86)\Steam\userdata\<id>\91xxxx\remote\out\save\s a v_0.sav
And if you are playing it on your local PC (Windows 7), save games should be at the following path:
C:/Users/<username>/Local Settings/Application Data/
Hop it helps
