The digital signature is corrupted

If you're trying to install the latest update of Ultimate Suite while there's an old version of the add-in previously installed on your machine, you might get this error message:

Even though our certificates are trusted, some antiviruses may block Ablebits sometimes. To fix the issue, please do the following:

• Check that the Office Data Apps certificate is valid.
• Go to Quarantine in your antivirus and restore all the Ablebits files you'll find there.
• Add the Ultimate Suite installation folder to your antivirus exclusions.
