Hi,
You can try to use this tool: Assembly Binding Log Viewer (Fuslogvw.exe)
Run this tool and view the contents of the Assembly Binding Log, the information can help you diagnose why the .NET Framework cannot locate an assembly at run time.
Hope it helps.
Please remember to mark the replies as answers if they help and unmark them if they provide no help.
Yours sincerely,
