Sitecore Experience Commerce - The service cannot accept control messages at this time

During the installation of Sitecore Experience Commerce, the following error would sometimes occur when attempting to re-run the installation script after it had failed previously:

TerminatingError(Start-WebItem): "The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: The service cannot accept control messages at this time. (Exception from HRESULT: 0x80070425)"

This error is caused by the Sitecore 9 IIS web site being stopped, which stops a package being installed as part of the installation process. Starting the Sitecore 9 IIS web site and waiting a few seconds, then re-running the installation script should work.
