Because of the Google Drive API changes in May 2024, the old versions of Backup4all (v.5 - v.8) will receive this error message when trying to select Google Drive as backup destination.
If you use version 5, 6, 7 or 8 of Backup4all, you will see the following error when you try to use Google Drive as backup destination.
As a solution, we recommend to upgrade to the latest version of Backup4all from this link: https://www.backup4all.com/upgrade.html
We currently develop only the latest version of Backup4all that is why the older versions will not be fixed.
