Question:

After installing Helpdesk 10.x and later, we get a 500.19 error on our IIS server



Answer:

You need to install .NET Core hosting bundle that includes "Asp Net Core Hosting module" https://www.jitbit.com/dotnet-hosting-bundle-8

Even if it is already installed, running a "repair" install and restarting IIS after that should help.
