Part 2: How to Install and Activate StoreEngine Pro
If you have already completed Part 1, StoreEngine Free is active on your site. Now follow the steps below to install StoreEngine Pro on top of it and activate your license key.
Important: Do not deactivate or delete StoreEngine Free. Both StoreEngine Free and StoreEngine Pro must be active at the same time for the plugin to work correctly.
Step 1: Purchase StoreEngine Pro
After a successful payment, Kodezen will send a welcome email to your registered email address containing your login email and password. Use these credentials to log in to your Kodezen account.
Step 2: Log In to Your Kodezen Account and Download StoreEngine Pro
Log in to your Kodezen account to download the StoreEngine Pro plugin file.
- Visit store.kodezen.com and log in using the credentials from your welcome email.
- After logging in, you will be taken to your account dashboard.
- Locate StoreEngine Pro under your purchases and click the Download button to save the ZIP file to your computer.
Step 3: Upload and Install StoreEngine Pro in WordPress
StoreEngine Free is already active on your site. You will now install StoreEngine Pro as a separate, additional plugin alongside it. Do not remove or deactivate the Free version during this process.
- Log in to your WordPress admin panel.
- Navigate to: Plugins → Add New Plugin
- Click the “Upload Plugin” button at the top of the page.
- Click “Choose File” and select the StoreEngine Pro ZIP file you downloaded from your Kodezen dashboard. Then click “Install Now”.

After this step, go to Plugins → Installed Plugins. You should see both StoreEngine and StoreEngine Pro listed, and both showing as Active.
Step 4: Copy Your StoreEngine Pro License Key
Retrieve your license key from your Kodezen account.
- Return to your Kodezen account at store.kodezen.com.
- From your dashboard, click on the License Keys section in the sidebar.
- Your StoreEngine Pro License Key will be displayed on this page. Click to copy it.
Your license key is a unique alphanumeric string. Do not share it publicly or use it on more sites than your plan allows.
Step 5: Enter and Activate the License Key in WordPress
This is the final step. You will paste your license key inside the StoreEngine settings in WordPress to unlock all Pro features.
- In your WordPress admin sidebar, click StoreEngine.
- From the StoreEngine menu, click License. The path is:
StoreEngine → License - You will see a License Key input field on this page. Paste the license key you copied from your Kodezen dashboard.
- Click the “Activate License” button.
Your StoreEngine Pro license is now activated. All Pro features are unlocked — including subscriptions and installment billing, affiliate management, memberships and content access, digital downloads with license control, order bumps and funnels, cart abandonment recovery, multi-currency, multi-vendor marketplace, Point of Sale (POS), invoicing and tax management, and advanced analytics.
