I am creating project on attendance system using QR Code scanning and I use Python to create it.
I used all needed libraries in the program like, cv2 , numpy , pybase64 , pyzbar .

But I am getting this above Error in the Pyzbar.

I got solution for this issue. I was facing similar issue just installed Visual C++ 64 bit version on my computer and restarted. Choose between vcredist_x86.exe or vcredist_x64.exe based on your machine.
