Hi @Leonardo Rotondo,
You will need to update your community URL in your Client Area.
Log into your Client Area -> you should see 'Manage this purchase' -> click 'Change Licensed URL' under the Licensed URLs heading.
Before you update the licensed URL, you will need to ensure that your current installation of Invision Community has been deleted/removed. You will then have the ability to update this field with your new URL, upload the files again and proceed with installing the forum software.
If you have any further issues, please don't hesitate to reach out.
