You do not have privileges to view this page error

I have three components deployed for a custom solution composed of a custom record, a workflow, and a workflow action script. When an opportunity is created and saved, the workflow fires, the action script is run for some custom logic, and the workflow continues on to create a task.  All of these components work perfectly together when deployed in "Testing" mode when logged in as me (administrator).

However, when I deploy everything in "Released" mode, I get the error "You do not have privileges to view this page", and this occurs even for me (administrator).  The custom record has no privileges, and the workflow is currently set to "Execute as admin".  I can have the workflow in Released mode and the action script in test mode, and everything works.  The problem is when I deploy the action script as Released instead of Testing.
