I need 100 downloads for my app

I have this new app on Google play. I already made advertisement for the app and I have until now about 3000 click to my app. And yet i only have 12 installs :( I'm thinking maybe the reason is because the app has very few installs to the point that when people see how little installs the app has they decide not to download it. So I need a good healthy installation rate, something good enough that will encourage other people to install the app. (I'm guessing near 100+ installations)
