After you get a license, the latest encrypted package is in your client area — download it and install it on your site.

Get your license: create a free one or buy a plan. Your license key appears in your client area.
2
Open the license in your client area and download the latest encrypted package (ZIP) — the version and date are shown.

Install it on your site (upload it in the control panel), then activate it with your license key. One license is valid for one site.

About

What Software Licensing Pro does

Software Licensing Pro turns WHMCS into a full software-licensing platform. Issue license keys for your own applications and validate, activate, reissue and expire them — each bound to a domain + IP and backed by a signed local key for offline validation.

A WHMCS provisioning server module creates and manages licenses automatically from your product orders (create / suspend / unsuspend / terminate / renew / change package), while the admin addon is a command center: dashboard analytics, licenses, product rules, feature entitlements, downloads, activations, reissues, a configurable expiry engine, webhooks, roles & permissions, health, audit and validation logs, and settings.

Developers integrate through a REST licensing API, a drop-in PHP SDK, webhooks and signed canonical requests (nonce + HMAC), with SSRF-guarded outbound calls. The whole UI is bilingual (English/Arabic, RTL) with light/dark themes and a client license portal, and is protected by CSRF, rate limiting and nonce replay protection.

Program code is ionCube-protected and self-licensed through InfinityInstaller with a signed protocol (compiled-in RSA key, nonce, issued-at freshness, product/domain/IP binding) and offline grace — one license per WHMCS site.

Requirements

WHMCS 8.x — install the admin addon + the provisioning server module (and the client-area nav hook).
PHP 8.1, 8.2 or 8.3 with ionCube Loader 12 or newer.
The WHMCS MySQL/MariaDB database (the module creates its own mod_slp_* tables).
Outbound HTTPS to infinityinstaller.com for the self-license check.
