User getting error: "_priv_gst_plugin_load_file_for_registry: module_open failed"

I have an app using GStreamer, and a user reported getting this error on Windows when they try to play videos (they get audio, but the video is blank):

This usually means Windows was unable to find a DLL dependency of the plugin. Please check that PATH is correct.
You can run 'dumpbin -dependents' (provided by the Visual Studio developer prompt) to list the DLL deps of any DLL.
There are also some third-party GUIs to list and debug DLL dependencies recursively.

They’ve already tried several versions (1.26.0, 1.25.1, 1.24.10, 1.24.0). They’re using the 64-bit MSVC installer and choosing a complete installation. I’ve tried the same thing with 1.26.0 on Windows, but I can’t reproduce the problem, so I’m not sure how to help the user.

Could anyone please help advise how to narrow down what’s going wrong here? The error message does suggest using dumpbin, but I’m not sure how to tell which plugin is having trouble in order to know which plugin to run it on.

If they can reproduce it, you could ask them to delete the registry file and then run gst-inspect-1.0 again with GST_DEBUG=GST_PLUGIN_LOADING:6 to get more info, or --gst-debug=....

Perhaps it’s also enough to check gst-inspect-1.0 -b which should list plugins that failed to load.

Hello, I am the user having the issue in question, and have the 1.26.0 one installed right now.

I am not sure if it’s the right way to do since I have no experience whatsoever, but if I open a PowerShell window in C:\Program Files\gstreamer\1.0\msvc_x86_64\bin and enter .\gst-inspect-1.0.exe -b, I get this:

(gst-inspect-1.0:1644): GStreamer-WARNING **: 16:04:11.447: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though.

(gst-inspect-1.0:1644): GStreamer-WARNING **: 16:04:11.462: Failed to load plugin 'C:\Program Files\gstreamer\1.0\msvc_x86_64\lib\gstreamer-1.0\gstpython.dll': Belirtilen mod?l bulunamad?.

If there are any steps I am supposed to follow, could you please tell me in detail? Much thanks in advance!
