Hi @Rick Weaver. We thank you for your reply regarding the previous questions asked by Jandy.
I have checked and it seems you have currently engaged in chat with one of our technicians. You have been given a hotfix right? May I ask if it worked to resolve your issue?
By the way, just a quick question to verify if I'm correct. Are you experiencing the issue whenever you click on the "Update Now" button at the center of your Trend Micro program window? If not, share with us on how you do the update.
To further help you out, try restarting the Trend Micro components first. See if this solves your issue
