In a recent customer installation we ran into an error “Required IIS module AspNetCoreModuleV2 missing” when trying to install the WebClient components in the Dynamics 365 Business Central version 22 setup.

Now the module should show up in the IIS Modules:
The installation of the WebClient components should now work as expected.
