How to generate License key for licensed products?
To generate the license key for v31.1.17 or later follow the below steps:
As of the 2025 Volume 3 release (v31.1.17), Syncfusion® introduced new editions of Essential Studio:
- Essential Studio UI Edition
- Essential Studio Document SDK
- Essential Studio PDF Viewer SDK
- Essential Studio DOCX Editor SDK
- Essential Studio Spreadsheet Editor SDK
- Essential Studio Enterprise Edition (all of the above together)
Change:
- Previously (before v31.x), license keys were generated per platform (e.g., ASP.NET Core, Blazor, Angular, etc.).
- From v31.1.17 onwards, license keys are generated per edition (UI Edition, Document SDK, etc.).
Customers who purchased or registered before v31.1.17 can still generate an Enterprise Edition license key, which will unlock all products.
How to Generate License Keys
For v31.1.17 or higher (edition-based)
Step 1: Go to the Downloads and Keys page.
Step 2: Click the Get License Key link.
Step 3: In the pop-up dialog, select version 31.x.x or higher.
Step 4: Select the edition or SDKs you need from the dropdown. You can select one or more based on the component usage in your application.
- For customers who purchased or registered before v31.1.17, you will see all the editions and SDKs.
- New customers who buy Essential Studio Enterprise Edition will also see all these editions and SDKs.
- New customers who buy particular editions or SDKs can only see those.
In order to generate the Enterprise Edition key, select all these options:
- UI Component Suite
- Document SDK
- DOCX Editor SDK
- PDF Viewer SDK
- Spreadsheet Editor SDK
Note: Customers who purchased before v31.x.x are strongly advised to select all 5 editions and SDKs while generating a key for v31.x.x or higher because your application might be using the controls or libraries from all of them.
Step 4: Click Get License Key. This generates the Enterprise Edition license key, which covers all SDKs and UI components.
Generating and Using Multiple License Keys
In v31.1.17 or later, if you have purchased multiple editions or SDKs separately and are using them in a single application, you must generate and use multiple license keys.
When this is required
This applies when your application uses components from more than one edition or SDK, such as:
UI Edition and PDF Viewer SDK
Document Editor SDK and UI components
Generating multiple license keys
You must generate license keys individually for each purchased edition or SDK.
Repeat the license generation steps for each edition
Each selection generates a separate license key
Example:
UI Edition → UI_LICENSE_KEY
PDF Viewer SDK → PDF_VIEWER_SDK_KEY
Registering multiple license keys
All generated license keys must be combined and registered together at the application entry point.
Supported separators:
Semicolon (;)
Comma (,)
Both separators are supported.
registerLicense('UI_LICENSE_KEY;PDF_VIEWER_SDK_KEY;DOCX_EDITOR_SDK_KEY');registerLicense('UI_LICENSE_KEY,PDF_VIEWER_SDK_KEY,DOCX_EDITOR_SDK_KEY');Important notes
All required license keys must be registered together in a single call
Ensure that all editions used in the application are included
Missing license keys may result in license validation errors
