If you've uploaded a third-party app like "Standard Accounting Report" by Florent de Labarre to your Odoo 10 instance, ensure it's placed in the designated "custom-addons" directory and added to the "addons_path" in the "odoo-server.conf" file. After restarting the Odoo server, log in as an administrator, navigate to the Apps section, and click "Update Apps List" to refresh. Confirm that the module's manifest file, like "manifest.py," is correctly formatted and specifies dependencies. Clearing the cache and checking server logs for errors can also aid troubleshooting. By following these steps, you should successfully integrate the third-party app into your Odoo environment.

Thank you very much for your reply.

I have done the same, copied 2 separate folders (account_standard_report and report_xlsx) in default addons directory, restarted the server and with administrator right and active developer mode tried to update the list) as it has been mentioned in the video that you have referred me but it hasn't worked.
