System.DllNotFoundException on Win7

[whgfu]

This program is directly compiled using a demo. Under. net8, the compiled program works normally on both win10 and win11, but win7 prompts System DllNotFoundException: Unable to load DLL 'Photino.Native' or one of its dependencies, But I can confirm that my directory contains Photino The Native.dll file.

May I ask how to handle this issue?

Application: HelloPhotino.NET.exe
CoreCLR Version: 8.0.724.31311
.NET Version: 8.0.7
Description: The process was terminated due to an unhandled exception.

Hi @whgfu, please use the Fusion Log Viewer to determine which DLL exactly creates the issue and provide this information to us. https://learn.microsoft.com/en-us/dotnet/framework/tools/fuslogvw-exe-assembly-binding-log-viewer

Please use the Fusion Log Viewer tool as mentioned above to determine what is missing. We don't support out of support OSs, but if you can determine what's not loading correctly, we may be able to suggest a work-around.

Do I have to install visual studio on the target machine to get this tool?
