Basically as it says in the title. I have installed the Forms package and have a license in umbraco/Licenses which covers localhost. When I run it straight from dotnet run, eg, localhost:17925 it works fine. When I publish the site and run from an IIS website which calls the published folder, using localhost:80, it does not seem to find the License - which does seem to be still there in its Licenses folder - and just show what looks like Angular placeholders in the Forms area. In Console it has:

Error: [$controller:ctrlreg] http://errors.angularjs.org/1.8.0/$controller/ctrlreg?p0=UmbracoForms.Dashboards.FormsController

When I click through on that error I get to an Angular error reference which shows:

The controller with the name 'UmbracoForms.Dashboards.FormsController' is not registered.

I am very new with v9 so really am not sure how this is supposed to work.

Last entry in Log file is as follows but not sure it is relevant
