Problem: Issues with ActiveX controls when launching ArcMap

Description

When launching ArcMap, there are issues with ActiveX controls. The issues are as follows:

  • ArcMap does not launch or crashes when internet security settings are set to High in Internet Explorer.
  • Errors occur when connecting ArcMap through Citrix via a remote connection. When ArcMap is launched, one of the following error messages is returned:
Error:   
Content within this application is being blocked by Internet Explorer security configuration, about: security_ArcMap.exe.
Error:   
One or more ActiveX controls could not be displayed because either: 1) Your current security settings prohibit running ActiveX controls on this page, or 2) You have blocked a publisher of one of the controls. As a result, the page might not display correctly.

If a similar issue occurs in ArcGIS 10.5, users may refer to the following Microsoft Help page: Windows Security Warning - ArcGIS 10.5. The defect, BUG-000105427, indicates that the issue will be fixed in ArcGIS 10.6. For more information, refer to GeoNet: ActiveX error warning.

Cause

ArcGIS Desktop is dependent on ActiveX for rendering graphical user interface (GUI). Disabling or preventing ActiveX from running results in incorrect functioning or complete failure of the software.

  2. Navigate to Internet Explorer > Tools > Internet Options, and click the Security tab.
  3. Click the Local intranet icon.
  4. Click Custom level.
Internet Options Security tab
