Add-in ribbon buttons are disabled

If the TagniFi add-in is visible in Excel, but all ribbon buttons for the add-in are disabled, your Excel model may be running in "compatibility mode". In this mode, you will also see that the Home -> Add-ins button is disabled.

To fix this, follow the follow steps to upgrade the Excel file:

  1. 1Make a copy of your Excel model as a backup. Go to File -> Save As and save as a filename different to the current file. This step is important in case the upgrade causes data loss in your file.
  2. 2Go to File -> Info. If compatibility mode is enabled, you will see message similar to:

  1. 1Click Convert. Then click OK if a confirmation dialog is shown. And finally, choose to re-open the file.

  1. 1The Excel model should now be compatible with the TagniFi add-in. See Installing the TagniFi for Excel Add-In for further information on starting and signing in.
