Excel COM add is not loading during startup and have to add it manually

问题

Excel COM addin is not loading during starting up and each time I have to add it manually. After checking the File > OPtions > Add-ins > Manage -> COM addins, I see that the 'add in' is in 'Unloaded' state. Not sure how to make it automatically load at startup.

Here's what fixed the issue for me.

Steps:

1. Start > type 'regedit'

2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\Addins

3. Then change the value of loadBehaviour to 3 for HyperionComAddin. As shown below. Just to clarify, this is the add-in that was not loading during start up for me. Picture in the question is to give an example.

4. Close registry and reopen it to make sure that value has not changed.

5. Now restart excel.

This also works for Microsoft Dynamics Excel Add In (VSTO). Upon doing above and change loading behaviour 0 to 3, closing Reg Edit, re open EXCEL, the Dynamics Add In is up, showing Dynamics TAB

It's also worth adding that the add-in has to be a trusted document or be located in a trust
