OCX not started

I'm using Windows 10. I've develop an OCX, which will open a video window in an Internet Explorer page

The OCX was running all the time perfectly, also under Win 8.1 on other systems and other Win 10 systems. So, I know it's working !

In order to have a better pdf presentation I installed the Adobe Reader. But with that software some shitty advertisment sw was installed. It seems that this sw was also using the IE.

I deinstalled the ad software and now my own ocx plugin is not started anymore. The sw must have removed something or must have set certain flags, which don't allow to start my own ocx.

Of course, I've set the activeX buttons in the advanced menu of the IE11.

Also debugging doesn't work anymore. That means the activeX plugin is not even started. No error messages. The activeX plugin ist registered as administrator, yes.

How can I fix it ? is there something in the registry ?

Maybe it has to do with rights, permissions, restrictions. I don't know.


Or do I have to do format c: ?
