pyzbar: FileNotFoundError: Could not find module 'libzbar-64.dll' (or one of its dependencies). Try using the full path with constructor syntax.
Thanks for this wonderful tool.
I am using Python 3.8.3 (default, Jul 2 2020, 17:30:36) [MSC v.1916 64 bit (AMD64)] on Windows 10.
After pip installing pyzbar I have got the following dll import errors:
Traceback (most recent call last):

anaconda3\lib\site-packages\pyzbar\ conatins both .dll (libiconv and libzbar-64). I have tried
`os.add_dll_directory(r"C:\Users\xxxxx\anaconda3\lib\site-packages\pyzbar")
` But it does not solve the issue.
Can you help me please?
Best regards, giacomo

I had the same issue, till I read all the README and then I found:
Installing vcredist_x64.exe solved the issue for me.
For others finding this the link (for me at the moment) for the redistributables is https://www.microsoft.com/en-gb/download/details.aspx?id=40784
It was already installed on my system. I was getting the same error when installing from conda (
conda install -c conda-forge pyzbar). What solved for me was to uninstall the conda package (conda remove -c conda-forge pyzbar) and install pyzbar through pip (pip install pyzbar).Since using pip inside a conda env is not recommended, I grabbed the DLL files (
libiconv.dllandlibzbar-64.dll) from the pip installation, uninstalled the pip package (pip uninstall pyzbar), installed pyzbar again from conda-forge, and pasted the DLL files into the folder shown in the error message.That said, how can those DLL files be included in the conda-forge installation?
yes its works man, thanks buddy "If you have this error download and install ms visual C++ 2013 "
i get this error and fix it with https://www.microsoft.com/en-gb/download/details.aspx?id=40784 but uninstall pyzbar before!! if not do uninstall, its not work
if you’ve already installed the pyzbr library, first uninstall (pip uninstall pyzbar) & then download the vcredist_x64.exe and install it
I spent hours to solving the problem and this worked. Thanks a lot. However, the interesting thing is why these files were not downloaded when installation with conda
thats work
