We had in one of our test environments a client where all agents under client were repeatedly in the logs with the Auto Installer. Upon further investigation, the agents in questions all were missing one package from the approved software list.  The package was the 7Zip-Install package on the Chocolatey Community Repository.

And their in lies our problem, In fact 7Zip-Install is not on the Chocolatey Community Repository, 7Zip.Install is.

A simple typo in the approved applications list will cause a package to fail install and will trigger the auto installer to try again each day until resolved. Check your repositories and make sure package names are correct if you see a daily repeating auto installer log.
