I am getting a message "uiWinMgr.exe has stopped working" when I try to open the Trend Micro program. How can I repair this problem. I'm assuming the program is continuing to protect my computer, but I can't tell for sure. Thanks.

Hi, Tom Emmelot. I hope we're doing fine today. :)

Hello, linda970. Welcome to the Community!

Getting a uiWinMgr.exe error is quite common and one of the reason is that there must have been a corrupted file in the Trend Micro folder so Tom Emmelot's suggestion to reinstall the Trend Micro program is correct. Kindly make sure as well that there are no other security programs installed on the computer so that we can make sure that there's no program that might cause performance issues with the Trend Micro program.

If you encounter problems during or after the installation, you may contact Best Buy's Geek Squad for assistance.

Have a great day!
