Cannot get Xcode archive Distribution to install on iOS Device

When I airdrop my archived app to my device it runs perfectly. But when I try to share with colleagues using the manifest.plist in a website link, the app will not install (Even on the same device where the airdropped app did). I get "Unable to Install [app name]"

Any help with this will be appreciated.

Here is my manifest.plist:

`<?xml version="1.0" encoding="UTF-8"?>
