FAQ

An unhandled exception of type 'System.BadImageFormatException' occurred in Winsoft.Ocr.dll
It's caused by using incorrect ocr.dll library, i.e. 32-bit instead of 64-bit or vice versa.
Select x86 or x64 platform in Visual Studio accordingly to the ocr.dll library and rebuild your application.
Or place proper ocr.dll to the folder where is your application exe file located.
32-bit ocr.dll is located in subfolder DLL\32bit
64-bit ocr.dll is located in subfolder DLL\64bit
