Usually that's due to a dependency like the onnxruntime.dll not being found.

Hi @skottmckay, I've tried using the setdlldirectory and checked the process explorer, found the onnxruntime.dll being loaded from the bin folder but when I try to deploy the app in other PC this issue is persistent there. Is there any other fix for this?
