Like an excited child at Christmas I've downloaded and installed the latest release of Nintex 2016 to my dev box. Gone to a custom list, clicked on the Nintex Forms button in the ribbon and...
....nothing! The button is unresponsive (pun intended).
I can click the down arrow to customise my item form but when I click that, nothing. The form designer will not load.
It was working fine before.
In Nintex Administration If I click on the "Form designer experience" link or the "Responsive forms template" link, I get a "Sorry, something went wrong" error.
Could not load type 'Nintex.Forms.SharePoint.AdministrationPages.DesignerExperience'.
The other pages in admin appear to work fine.
There was no error during the install process.
