Specific .apk not installing on Android Lollipop??

[Chase Patrick]

Hey,
I have an HTC M9 for Android. I have Lollipop. I have unknown sources checked.

I have been able to download apks in the past, and other apks now.
I am currently attempting to install a new Remote Play apk (for Playstation) on this device.
I am downloading it directly from Dropbox and when it opens up Package Installer and requests permissions, it allows me to click "Install".
It appears to load for a few moments, saying "Installing" with the loading bar, then it stops and says "App not installed", with an X by it.

Any help would be appreciated. This seems like a simple problem to fix hopefully.
Thanks in advance

Check with the app developer. He might have some insight.

Welcome to the forums. Does the app come up in Play?
