Background

Microsoft Office/Access and organizations have increased security on PCs to limit phishing and other exploits. One of the areas is restricting the use of ActiveX controls. While that may make sense for products like Excel, Outlook and Word, database applications are more sophisticated and often need ActiveX controls to show data and provide a better user experience. 

Problem

As a result of such ActiveX restrictions, the Documentation Explorer form in Total Access Analyzer may be blocked and trigger Error 2926 in procedure clsTreeviewExplorer_TAA.Initialize:

Because of your security settings and current security policy, this control is disabled.

Our Documentation Explorer uses a Treeview control to show the hierarchy of your database objects.

Solution

Fortunately, there's a simple solution to reset Access to work the way it did before under the Trust Center Settings:

1. Run Access
2. From the left bottom corner, click Options
3. From the Access Options form, click Trust Center in the lower left, and the [Trust Center Settings...] button:
   
4. Then click on ActiveX Settings on the left border:
   
5. If the setting is on the first item (Disable all controls without notification), change it one of the other items. We generally use the last two items for Prompt me or Enable all.
6. Restart Access.

Please let us know if this doesn't resolve the problem.
