If what @Zombeaver said to try isn't the problem, right click the file, choose properties, and click the button Unblock. That button will only be there if Windows marked it potentially dangerous because it was downloaded from the internet. 

Thanks this worked, necer had to do that before, must be new...

[Unable to install Launchbox 6.11]

I just downloaded the .exe file, but when I select it, nothing happens.  I have tried repeatedly clicking on it, running it in compatibility mode, and running it as an adminstrator but to no avail. Do you guys have any idea of how I could fix this?
