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.
