Answer 2

This solved it for me:

Go to the following registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\15.0\Common\COM Compatibility{8856F961-340A-11D0-A96B-00C04FD705A2}

Then set the value data from 400 to 0.

Hope it helps.

Answer 3

We have had a similar problem in the past with an ActiveX control that we insert on an Excel sheet from our COM Add-in, and you seem to have touched on two of the items (below) to solve it. The following solves the problem most* of the time.

From Excel 2010: File ribbon; Options; Trust Center; Trust Center Settings (button)...;

• Add-ins: UNCHECK 'Require Application Add-ins to be signed by Trusted Publisher'.
• Macro Settings: Ensure it is not disabling all Macros without notification. It is OK if it is set to 'Disable all Macros with notification'.
• ActiveX Settings: Ensure it is not disabling all controls without notification. It is OK is it is set to 'Prompt me before enabling all controls with minimal restrictions'. THIS WAS THE MAIN CAUSE.
• Trusted Locations: Add the directory of your control.

Note that some of these are usually not necessary if InstallShield properly registered the containing program (e.g. dll). Also notice that we still allow prompting (probably a good idea to pretect your liability). That has not caused us a problem.

• However, the reason I am here is that we have one case (out of 200 customers) where the above did NOT work and this just started happening a week ago (it was working for the last 9 months). I am assuming Excel corruption at this point since there were no changes. We have otherwise tried everything. Did you resolve yours?

I suffered from this problem the other day and went back to basics with my solution as I don't like the idea of editing the registry.

I solved the problem by simply re-registering the main types of controls I use i.e. Command buttons, Comboboxes, Listboxes, Spinners etc.

To do this go into the Developer tab and click on Insert (a control)

By choosing 'More Controls', in the bottom right-hand corner of the Activex Controls, you can re-register any controls that you might need.
