In order to distribute your application to end-user, please obtain Runtime licenses from your sales manager.
The Runtime license has the number, different from your Developer license number. But you don't need to modify your source code to put that different number inside your application. During all time of the Development process, starting from code sample and ending by the production version, use the same Project ID for InitializeEngine() method call.
For FineReader Engine 11 and FlexiCapture Engine 11
Your Project ID is XXXX-XXXX-XXXX-XXXX-XXXX-XXXX. It is the same as your Master Developer License.
For FineReader Engine 12 and FlexiCapture Engine 12.
Your Project ID is a sequence of 20 letter-numeric characters.
In order to use Runtime license, make sure that FineReader Engine licensing service is installed on the target computer and the Runtime license is activated on that computer. License manager will find the installed license automatically. You don't need to put the number of that license in your application code.
