--- title: "License for different bundle ID | Nutrient" canonical_url: "https://www.nutrient.io/guides/web/knowledge-base/license-registered-different-bundle-id/" md_url: "https://www.nutrient.io/guides/web/knowledge-base/license-registered-different-bundle-id.md" last_updated: "2026-05-18T15:18:35.785Z" description: "License registered for a different bundle identifier guide for Nutrient Web SDK with detailed instructions and code examples." --- You might see the following license error: NutrientError: Failed to initialize NutrientViewer: Invalid license key. Failed to activate NutrientViewer for 'example.domain'. Error: Your license has been registered for a different bundle identifier - not "example.domain". Each NutrientViewer license is only valid for one explicit bundle ID and one distribution method (Enterprise or public App Store). Please contact sales at https://www.nutrient.io/contact-sales with your requirements for a new license. ```` This error can be caused when you have both `example.domain` and `www.example.domain` licensed. Since you’re using the same license key for both domains, it can cause the error to happen intermittently, depending on whether the visitor uses `www.example.domain`. Safari simplifies the domain that’s shown to you, so unless you click the address bar to show the full URL, it might show you `example.domain/`, even though it’s accessing `www.example.domain`. To make sure you’re loading the correct license key based on the domain your users are visiting, use something like the following: ```js let licenseKey = null; if (document.location.host === "example.domain") { licenseKey = ""; } else if (document.location.host === "www.example.domain") { licenseKey = ""; } else { console.error("Invalid location -> escalate to ops"); } ```` We’re working on improving this error message so it’s clearer. Additionally, it’s generally recommend to use a web app on only one subdomain — either www or no subdomain — as this can reduce potential problems.
