MS CRM 2011 – Custom Workflow activity not available

Registered a custom workflow successfully but it didn’t show up in the list of available workflow steps. Restarted async service, restarted iis, even created a new key and went through the whole process again. Nothing worked.

Appears I was using the URL without the organisation name i.e.

http://localhost/MCSCRM2011

rather than

http://localhost/[organisation name]
