OCRExtractRelative - Error: Specified native messaging host not found

Whenever trying to run a Macro step with OCRExtractRelative, “Error: Specified native messaging host not found” is logged and the macro fails. I have Online OCR enabled under the settings. I tested out with the DemoPDFTest_With_OCR Macro, and recieve the same error. What may be the cause?
I am using Kantu extension for Chrome on Windows.

OCRExtractRelative not only uses OCR, but it also needs image recognition to find the area to OCR.

=> You need to install the XModules


…then the error should go away!
