these applications are typically not from the App Store, but I am not simply prompted if I ":want to trust" but rather forced to trash it. I have attempted to set my preferences to allow the downloads of App Store and other developer files, but it seems to have no impact. examples: google chrome, adobe acrobat reader, etc....

typically a slow internet connection is a one way for .dmg downloads to become corrupt/damaged.

Try a faster Network if yours is suspect or an Ethernet connection in an effort to resolve.
