Nintex Workflow was giving an error, when trying to publish: “There was an error installing the content type required for the Flexi-Task action. Please arrange for an Administrator to run the following command on the server: stsadm.exe -o installfeature -n nintexworkflowcontenttypeupgrade For more information please contact [email protected]“
I already ran that command: stsadm –o installfeature –n nintexworkflowcontenttypeupgrade, as in the error screen. it completed with “Operation completed successfully!” but still had the same error!!
Then I tried activating it:
stsadm -o activatefeature -name nintexworkflowcontenttypeupgrade -url http://sharepoint.crescent.com/sites/finance/ -force
and things are turned good!
