Seems like IE is ignoring you! So, I guess we can try and force it.
In Internet Options, on the intranet tab, click Custom level
Over half way down this list, there is an option called Launching applictions and unsafe files (not secure obviously but may help).
About 1/3 down are:
- Only allow approved domains to use ActiveX without prompt
- Download unsigned activeX controls
Under Active scripting, disable, enable or prompt as you like.
In Internet Options, click on the Advanced tab
Scroll down to the bottom to the security tab. In here, you can allow active content to run files on My Computer.
You could also try adding the site to the list of trusted sites and reducing the security level.
Also, if using a modern version of IE, you can turn on (or off for you) ActiveX Filtering in the Tools menu

The answer lies in the Group Policy editor, as does much of the in-depth configuration within Windows 10. Right-click the start menu button and select "Run"; from there type in "GPEdit.msc".
Go to "Computer Configuration" and "User Configuration" (do it for both) > Administrative Templates > Windows Components > Internet Explorer and find the option labelled "Prevent "Fix settings" Functionality". Set it to Enabled.
From there, reboot to receive one last security warning. It will be a screamer /!\ as opposed to a critical stop (X). Right-click it and select "Turn off notifications for this app". Next, open the Control Panel by right-clicking the Start Menu and navigate to "Security and Maintenance". Where it says "Internet Security settings", click "turn off messages about internet security settings".
After that you should be all done.
