ActiveX Custom Input Prompt

Help
1

HI, I have been hit with the activeX problem while using the custom input activity.
I have already looked at the solution given here:
How to disable the ActiveX prompt while using Custom Input Activity?

But adding the tag doesn’t seem to be working for me.
Also, I have changed all the internet options to accomodate ActiveX controls, but the prompt still shows up. I was wondering if there is any other fix to this.

@CADLAB
What version of windows are you running? What version of IE are you running?

I was able to get your html to load just fine without seeing the security popup.
I’m running:
Windows Server 2016 Datacenter
IE 11.3024.14393.0
