I'm trying to get Nintex Sign set up and working in my environment and I can't find the system/Nintex version requirements.
My Environment:
SharePoint 2013
Nintex Workflows Version 3.3.1.0
We do not have Nintex Live enabled. And the documentation for the Nintex Sign says that the settings are located in the Live and External Settings page in Central Admin.
What do I need to do to enable Nintex Sign? Upgrade Nintex Workflows? Enable Nintex Live? I can't find this information anywhere on the site.
