Checking to see if Disabled
Sometimes Excel, Word or Project will disable an add-in if it takes a while to load, causing the Spira Add-In to be listed under the 'Disabled Items' in the Options > AddIns dialog box. To re-enable an item listed as disabled, click on the Manage [Disabled Items] option from the dropdown list and then click the [Go] button. Then selected the disabled item and choose [Enable]. You will need to restart the Office application for the change to take effect.
