Failed to publish workflow for Email entity

I got error message after publish Workflow for email entity steps .

"An error occurred when the workflow was being created. Try to save workflow again"
after i try to publish workflow with email steps.

the reason can be installed rollup 2

the solution can be adding next rows to CRM 4.0 web config
