There are some instances where Internet Explorer 11 will not run an ActiveX script. This can be tested by going to the site www.activextest.com. If you receive a message indicating you are using Chrome or Firefox, then an ActiveX will not be able to run.
There are settings within IE which can cause this. The most common are:
- Enhanced Protected Mode
- ActiveX Filtering
- Initialize and script ActiveX controls not marked as safe for scripting
