When using our DLLs in an application, our referenced DLLs must be deployed in the same folder that has the application's EXE, even if the EXE is referencing the DLLs through another DLL, and not directly.

Please note that our components can only be used to create an end-user application. This means if you are creating components that will be used by other programmers, you will need LEADTOOLS SDK licenses for each programmer who uses these components.
