We are exploring Nintex Workflow 2013 trial version and it installed successfully.
We configured it as per installation guide i.e. configuring content database , web application activation, site collection features activation etc...
but when we are trying to activating Nintex Workflow 2013 Site Feature , we are getting Invalid license file. error .
Is this cause for nintex workflow option is not displaying in workflow settings ?
Let us know the solution .
