I am trying to open Transmission from which I've downloaded outside the Apple App Store. However, it keeps showing the error and I can't open it. I want to know if there's a way to open such applications even if its not downloaded from the App Store. If there is a possible way please let me know. The error I got is shown below:

"Transmission" can't be opened because it was not downloaded from the Mac App Store.
Your security preferences allow installation of only apps from the Mac App Store.
