Error installing custom Plugin

Hi

I am getting an error when installing my custom build plugin.
The plugin is working fine when running on my own development machine.
I have tried to give Full control to all accounts I can think of, including IIS_IUSRS

This is the error from the eventlog:

Application: w3wp.exe
CoreCLR Version: 5.0.421.11614
.NET Version: 5.0.4
Description: The process was terminated due to an unhandled exception.
Exception Info: System.Exception: Plugin 'GLS'. Access to the path 'C:\inetpub\wwwroot\Nop\Plugins\bin\Nop.Plugin.Shipping.GLS.dll' is denied.
Access to the path 'C:\inetpub\wwwroot\Nop\Plugins\bin\Nop.Plugin.Shipping.GLS.dll' is denied.

A bonus question: Why are the installation putting my dll in the bin folder?

Any ideas?

Best regards,
Axel

The rest of the error message indicates that Nop will try to delete the file first, and thats what causes the error to occur:

---> System.Exception: Plugin 'GLS'. Access to the path 'C:\inetpub\wwwroot\Nop\Plugins\bin\Nop.Plugin.Shipping.GLS.dll' is denied.
---> System.UnauthorizedAccessException: Access to the path 'C:\inetpub\wwwroot\Nop\Plugins\bin\Nop.Plugin.Shipping.GLS.dll' is denied.
   at System.IO.FileSystem.DeleteFile(String fullPath)
   at System.IO.File.Delete(String path)
   at Nop.Core.Infrastructure.NopFileProvider.DeleteFile(String filePath)

Which version are you using?

Depending on which version you’re using, you’ll be able make the following changes via either the admin, or app_settings file.

Disable ‘ Copy locked plugins to subdirectories on startup’ and also ‘ Use plugins shadow copy’.

Hello, and thank you for your answer.
It did take care of that error, but it just found a new error to throw:

Exception Info: System.Exception: Plugin 'GLS'. Assembly with same name is already loaded
Assembly with same name is already loaded

You know how to get rid of that?
I am using Nop 4.40

In File Explorer, Search from the root folder of you site for name:GLS
