Clear steps:
- Download and install normally the original mod Admin CP Honeypot (include outdated admin folder) following instructions on the first page.
- Once mod activated, delete the admin folder and copy the updated admin folder (for 1.8.10). It's not necessary to disable the mod before.
- Optional: install the french language pack (front-end mod), just replace admin/index.php file by new. You can easily modify index.php for other language...
