Office Add-In requirements lead to loading failure

Question

I can not set the requirements in the Manifest for my Word Plugin without either loosing the Add-in commands or the ability to run it.

My Manifest looks like this:

<?xml version="1.0" encoding="UTF-8"?>

      <!-- resources not listed to reduce amount of Code -->

  </VersionOverrides>
</OfficeApp>

I tried to set them in various places (see comments in Code). Unfortunately, it does not help. Either the Add-in crashes (without log) or does not display the ribbon bar items. I need to set the requirements as my features rely on API 1.3 and does not work in elder versions, so the Add-in does not get approved without it.

The above placement of <Requirements> is inspired by the docs. If I place it one element further up or down, the xml-validation fails. But where it is now, the validation tells me it should work.

Where do I have to place <Requirements> without breaking the Add-in?

Answer 1

The trouble here is that DefaultMinVersion="1.3" sets the default version for child elements. In turn, this means you're requiring a minimum version of 1.3 for TableBindings and Selection. The latest version of these two requirement sets is 1.1 so Word fails to load the add-in since it fails to meet your minimum version requirement.

What you need here is to specify WordApi with a minimum version of 1.3. Try using this instead:

<Requirements>
    <Sets DefaultMinVersion="1.1">
        <Set Name="TableBindings" />
        <Set Name="Selection" />
        <Set Name="AddinCommands" />
        <Set Name="WordApi" MinVersion="1.3" />
    </Sets>
</Requirements>
