The engine directory is optionally passed as the engineDirectory parameter to the L_OcrEngine_Startup method. The is the path to the folder containing the OCR engine runtime files.
By default, during setup the LEADTOOLS OCR Module setup installs the OCR engine files to "Installation Path\Bin\Common\OcrAdvantageRuntime" where Installation Path is the root folder where the LEADTOOLS for C API is installed (for example, C:\LEADTOOLS 19).
If engineDirectory parameter passed to the L_OcrEngine_Startup was NULL then LEADTOOLS OCR engine will look for these extra files in the default installation folder specified above.
