We’d like to provide some more details regarding the issue we're currently facing:
There was no OS upgrade. However, we did apply a Windows security update last week, and the issue started occurring after that.
Operating System: Windows 10 -1809
DPI Scale: 150%
TestComplete Version: 15.72.60
Re-installed TestComplete: Not yet reinstalled .Should i have to?
SmartBear Test Extension: Yes, installed and enabled.
Application Type: Desktop WPF application.
Champion Level 3"After upgrading our operating system" - this implies OS upgrade e.g. Windows 10 to Windows 11!
Refer to the requirements that scot1967 has provided, see https://support.smartbear.com/testcomplete/docs/general-info/configuring/windows-specifics.html
Your DPI and/or Scale needs to be set at 100%. Otherwise, TestComplete will fail to recognise objects. You can test this using the Object Spy tool, and you will see that objects are not correctly highlighted, as you hover over different UI objects.
As you have only installed an OS Patch, you don't need to re-install TestComplete.
