Creative Cloud packager packages failing

Our production network is off-line and never touches the internet. We create packages with CC Packager to install off-line with attached licenses and have never had a problem until this past summer. We can't get any packages to run. Each will spin away for a while, even install AE, Audition and Character Animator then fail and rapidly uninstall the three apps. I've reinstalled Packager (several times).

Any suggestions?
