well the exact problem is that, after downloading the game APK, i click on the "install" button, the game tries to install, but after severals seconds, i have a message that says "Application not installed." and... That's it. Even if i try again, i'ts not installing. And i'd like to specify that i agreed my phone to download apk and non certified apps.
Hmm, thanks alot for the details! Sadly we haven't heard of that one. Can you check if there's maybe an old version of Third Crisis already installed that you can uninstall?
