Missing .dll Mech-Vision function "Read QR Codes"

Q&A
1

Hello,

I tried to read a Data Matrix code with Mech-Vision and found out that there are two different functions to read such codes. The Read Bar Code function does not support Data Matrix codes. The Read QR Code function gives me the following error message:

[ QR ] Read QR Code_1: Load failed: C:/Mech-Mind/Mech-Vision & Mech-Viz-1.8.2/Mech-Vision/read2DBarCode.dllCannot load library C:\Mech-Mind\Mech-Vision & Mech-Viz-1.8.2\Mech-Vision\read2DBarCode.dll: The specified module could not be found.

Is there a way to read DM codes with the Read QR Code function and how can I solve the missing library error?

The step has been deprecated; you can now use the “Calc Results by Python” step to recognize DM codes with the help of pyzbar.
