On Launch, Pops Up Saying Running Off DMG, Is In 'Applications' Folder

When I launch Minecraft from the dock or from the Applications folder, it loads for a bit, then the Minecraft Updater pops up, saying:
"Unable to start Minecraft, if you are running from a dmg, please drag to Applications and try again"
The issue is that, as stated, I'm not running from a dmg. This even happens after making sure that both minecraft.app and it's 'contents' folder are read-write for my user.
