When trying to install an addon in Odoo, please ensure that you have correctly performed the following steps:

1. Copy the addon folder to the addons path: Make sure you have copied the extracted "Account_invoice_Factury" folder to the correct addons path of your Odoo installation. The default location for addons is usually odoo/addons or a custom path specified in the Odoo configuration file.
2. Restart the Odoo service: After copying the addon to the addons path, restart the Odoo service for the changes to take effect.
3. Update the addons list: Activate developer mode in Odoo. Then, go to "Apps" and click "Update Apps List". This will refresh the list of available addons and your newly added addon should appear.
4. Install the addon: Search for the "Account_invoice_Factury" addon in the Apps list and install it.

If you have followed these steps and the addon still does not appear, please check the following:

• Permissions: Make sure that the Odoo user has read and execute permissions on the addon folder and the files within it.
• Dependencies: Check if the addon has any dependencies on other modules. If so, you need to install those dependencies first.
• Compatibility: Make sure that the addon is compatible with your Odoo version.

Hope it helps.
