You get The option for the SharePoint 2013 Workflow platform is not available because the workflow service is not configured on the server. Please contact your server administrator even after installing and configuring Workflow Manager 1.0 for SharePoint 2013.

Please check the below things:

• Verify the hidden web scoped feature "WorkflowServiceStore" feature is activated on the site.

          Get-SPFeature -Limit All -Web htt://siteurl
           If you don't see the feature is activated, activate the above feature.

• Verify the Service Application associations of the web application in Central Administration whether it has a service connection "Workflow Service Application" 

  

Locate WorkflowHostUri

Recently I was doing Installation and Configuration of Workflow Manger 1.0 for SharePoint 2013 Designer Workflows.

After completing the Installation and Configuration there is another step to register the workflow service with SharePoint using Register-SPWorkflowService poweshell command.


Register-SPWorkflowService -SPSite 'SiteCollectionURL' -WorkflowHostUri 'workflowhostur'


WorkflowHostUri value is your the SharePoint Server's fully qualified name with port 12991
on which the Workflow Manager is installed.

To get the computer's FQDN name, right click on "My Computer" or "This PC", select "Properties" and see for Full Computer Name,
