Follow these steps to activate your DeltaOptimizer Pro license.
Visit our pricing page and choose a plan. Complete payment via PayPal and your license key will be sent to your email.
Launch the application. If you haven't installed it yet, download it here.
Click the "License" or "Activate" button in the app, usually found in the top-right corner or sidebar.
Paste your license key into the input field and click "Activate". Your key will look like this:
Once activated, all features are unlocked for the duration of your license. Your license is bound to your current device (HWID-locked).
Check your spam/junk folder first. If you still can't find it, wait 10 minutes for processing delays, then contact support with your PayPal transaction ID and we'll resend it.
Make sure you've copied the entire key including the "KEYAUTH-" prefix. Each key can only be activated once on one device. If you're reinstalling on the same device, contact support to reset your HWID binding.
Contact support with your license key and request a HWID reset. We'll unbind your key from the old device so you can activate it on the new one. This is free of charge.
Open the License page in the app and enter your key to activate. If the trial period ended before you activated, your settings are preserved — activation will restore everything.
ICC color mapping works best with SDR displays. For HDR displays, we recommend using the Digital Vibrance and Real-time Filter modules instead, which are fully HDR-compatible.
All payments are processed through PayPal's secure payment system. We never see or store your credit card details. Only your email and transaction ID are used for license delivery.
If the software fails to work on your system and we cannot resolve the issue through support, contact us within 14 days of purchase for a refund. Activated keys that work correctly are non-refundable.
