Public Class OCR Private _RasterDocument As RasterDocumentEngine Private _codecs As RasterCodecs Public Sub New() RasterSupport.Unlock(RasterSupportType.Ocr, "XXXXXXXX") '2 Concurrent Runtime Licenses RasterCodecs.Startup() _codecs = New RasterCodecs _RasterDocument = RasterDocumentEngine.Instance _RasterDocument.Startup() End Sub End Class Sub Main() Dim ocr1 As New OCR Dim ocr2 As New OCR End Sub    Report

Are there any settings required or any way to apply 2 concurrent licenses?

The only way to use multiple instances of the OCR engine on the same PC is to run completely separate instances of the application (running from separate processes).   Also, if you have an OCR session, you cannot access this session from multiple threads. The thread that creates the session and initializes the engine should be the same thread that adds a page and performs recognition, then shuts down the engine.   This limitation is from the OCR engine itself and cannot be overridden.
