My issue was resolved by Dell.  One of their support personnel remotely used Revo Uninstaller to remove all traces of Optimizer.  After that, it reinstalled successfully, ran, and I was able to disable the proximity sensor.  Thank you, Dell!
Howdy, I am on a brand new Latitude 7410 and in needs to disable Dell proximity via Dell Optimizer, but anytime I open the app I face the error messages shown below: [IMAGE][IMAGE]                     I have updated all Dell apps and ran Windows updates but I always get the same results. Also tried to reset/repair the app via Windows but nothing. Does any of you got into this error as well? Thank you!
