.NET Core app unable to start in IIS due to ErrorCode = '0x80004005 : 80008083

Question

I have a .NET Core application. It runs locally with VS2017 and Kestrel. It runs locally under IIS. However, on the server it fails to start with a 502.5 - Process Fai

Answer 1

Error code: 0x80004005 means a file missing or can't be accessed.

Sub-code: 80008083 appears to be a version conflict.

This error means a different version of dotnet needs to be installed on the server.
