ImportError：Could not find module 'libdmtx-64.dll' (or one of its dependencies).(windows)

[taoan-wang]

When using python under windows, an error occurred when I used from pylibdmtx.pylibdmtx import decode

the error is

FileNotFoundError: Could not find module 'libdmtx-64.dll' (or one of its dependencies). Try using the full path with constructor syntax.

I have installed vcredist_x64.exe，but it still has error.

System:

python3.8.18 64 bit
win 11 64 bit

I have the same problem on windows 10 using python 3.10.0 and pylibdmtx 0.1.10.
Any updates on this issue?

I got it fixed in windows installing:

Visual Studio 2013 (VC++ 12.0)
X64 | 12.0.40664.0 | vcredist_x64.exe

I also encountered the same error before. My solution is to install the vcredist_x64.exe before pip install pylibdmtx.
It then works for me.

Hope this can solve your error.

Couldyou find a solution? I'm getting the same error even though i installed vcredist_x64.exe.

I found a solution, use Dependencies GUI to figure out which dll is misisng in libdmtx-64.dll

• You can install in here https://github.com/lucasg/Dependencies/releases)
• After install extract and open DependenciesGUI.exe
• Open the libdmtx-64.dll path (Ex: C:\Users\<YourUser>\AppData\Local\Programs\Python\Python38\Lib\site-packages\pylibdmtx\libdmtx-64.dll) (I use python 3.8)

It will so you which dll file is lost in libdmtx-64.dll. For my case it's MSVCR120.dll it's losing
If you lost the MSVCR120.dll like me just install vcredist_x64.exe. Here are the link https://www.microsoft.com/en-us/download/details.aspx?id=40784

I hope this help
