I am having the same issue as in this thread
This is in a three-server development farm. I'm testing before upgrading production. In addition to the database server, the farm is a Central Admin server that is not running Microsoft SharePoint Foundation Workflow Timer Service, and a web front-end that is running the Workflow Timer Service. I am running the installation on the Central Admin server.
- Current Nintex Version 188.8.131.52
- SP Version 15.0.4849.1000 Windows Server 2008 R2, SQL 2012.
Running NintexWorkflow2016.exe, the installation completes without errors. However, in Central Admin, the Nintex Workflow Management section looks like this:
If you click on the top link, you get
"Something went wrong" The file '/_admin/NintexWorkflow/Management.aspx' does not exist.
So I followed the steps in the post above ( a "Correct Answer"), retracted all the Solutions using PowerShell. All solutions now show as "Not Deployed/None" on the Solution Management screen.
When I tried activating the core solution on CA, i got this:
Install-SPSolution : This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application.
So I tried deploying to all web apps
Install-SPSolution -Identity 'nintexworkflow2013core.wsp' -AllWebApplications -GACDeployment -Force -Verbose
and got the same error.
Please advise. Thanks.
