Internet Explorer – Automation Server Can't Create Object

Internet Explorer 8, 9, 10 and 11 all error with:

Automation server can’t create object

I found that to fix the Automation server error:

1. Go to IE -> Options and click on the Security tab
2. Select the zone that the website with the Automation server error is in
3. Click Custom Level…
4. Enable Initialize and script ActiveX controls is not marked safe for scripting

You should no longer get the Automation server can’t create object error.

For security reasons, it might be better to add the site (if you trust it) to the Trusted Sites zone manually, rather than enable the setting for all websites in the internet zone (assuming that’s where the erroring site is).
