Error: Could not find a suitable provider for dism

[Steve Tuttle]

So, I am wanting to ensure that the IIS-Webserver is present.  Seems like it should be easy enough.  I have installed https://forge.puppetlabs.com/puppetlabs/dism.  I have a class that looks something like this:

class someclass {

    dism {

                'IIS-Webserver': ensure => present,

     }

}

When I do puppet apply --noop tests/somefile.pp i get this error:

Error: Could not find a suitable provider for dism.

Obviously, I am missing something.  The dism module is installed, but it cannot be found when my class needs it.  If someone could enlighten me on how to sort this issue, i would be most appreciative.  It *should* work; but does not because my understanding is inadequate/incomplete.

Thank you.
