Facing HTTP Error 500.0 - ASP.NET Core IIS hosting failure (in-process) issue while hosting the application to IIS  server

You have setup the system and installed as per https://docs.nopcommerce.com/en/installation-and-upgrading/installing-nopcommerce/installing-on-windows.html

Any errors in the Windows System Events Logs  ?

1. Yes, I have set up the project as per the documentation
2. yes, I found  2 errors in the event viewer
Failed to start application '/LM/W3SVC/7/ROOT', ErrorCode '0x8007023e'.
Application 'D:\nopCommerce\nopCommerce_4.50.4_Source\Presentation\Nop.Web\bin\Debug\net6.0\' failed to start. Exception message:
The executable was not found at 'D:\nopCommerce\nopCommerce_4.50.4_Source\Presentation\Nop.Web\bin\Debug\net6.0\.\Site.Web.exe'

"Site.Web.exe" ??

Something's not right in your config (IIS?)  If anything, it should be "Nop.Web.exe"
