# Install WHMCS

Before start the instalation need to buy the [WHMCS License](https://reliablelicense.com/license/whmcs-license/) from [Our License Store](https://portal.reliablelicense.com/store/whmcs-license)

Our WHMCS license is IP-based, just like our other licenses. Unlike our other licenses, which are installed using a CLI command, the WHMCS license is activated by replacing the **License.php** file. Simply replace the original **License.php** file with the one we provide. Do not edit or rename the file. Click the **Download** button below to download your license file.

  [Download](https://api.reliablelicense.com/WHMCS.zip)

### For New Install

1. We always recommend downloading WHMCS from the official WHMCS website. Before downloading, please check the [version details](https://docs.whmcs.com/releases/) to make sure you choose the version you need. Click the button below to download your preferred WHMCS version.

^*You can also change the version or release number in the download link to download any WHMCS version you need.*

2. Now extract the license file you [downloaded](https://api.reliablelicense.com/WHMCS.zip). Inside the ZIP file, you will find the License.php file.

3. Connect to your website using FTP, or open the File Manager in your hosting control panel (*such as cPanel, Plesk, DirectAdmin, or Webuzo*). Upload the WHMCS ZIP file to your target installation directory or domain, then extract it.

4. Next, go to the following directory: `/vendor/whmcs/whmcs-foundation/lib` In this folder, you will find the **`License.php`** file. Replace the original **`License.php`** file with the **License.php** file we provided.

**Done! Your license is now active.**

You can now install WHMCS by following the official installation process.. During the installation, you can enter any random license key in the WHMCS installer. Your WHMCS will be activated automatically by Reliable License.

### For Existing Install

No changes to your WHMCS settings are required. Your existing data and settings will remain safe and unchanged, so you can complete the process without any worries.

1. Connect to your website using FTP, or open the **File Manager** in your hosting control panel (such as cPanel, Plesk, DirectAdmin, or Webuzo). Upload the WHMCS ZIP file to your target installation directory or domain, then extract it.

2. Next, go to the following directory: `/vendor/whmcs/whmcs-foundation/lib` In this folder, you will find the **`License.php`** file. Replace the original **`License.php`** file with the **License.php** file we provided.

3. Log in to your WHMCS admin area. Click the `Help (?`) icon in the top-right corner, then select `License Information`. On the `License Information` page, click the `Force License Update` button to refresh your license.

**Done! Your license is now active.**

### Note

- Our WHMCS license is only file-based and does not require a CLI command.
- The WHMCS license is activated by your server's IP address, not your domain name.
- To activate the license, replace the original WHMCS **License.php** file with the **License.php** file we provide.
- You can use a single WHMCS license for unlimited domains on the same server IP. There is no need to purchase multiple licenses as long as all WHMCS installations use the same IP address.
