    Hello,

    Please do try the following:

    - Use the search function in Business Central to find the page Office Add-In Management

    - In the page that opens, click on the three dots in the action bar, and then More Options

    - Click again on the three dots, and a new additional menu shows up called Actions. Click on it, and then Reset Default Add-ins

    After this, try again to deploy the addin using the assisted setup.

    Thanks.
