When trying to access the help files from the Designer, under Help > About, the following error occurs: Nintex.Workflow.HC.cab file cannot be found. Additionally, this error occurs when trying to install the files from command line.
- Verify that the Nintex Workflow 2013 Help and How-to files are missing in SharePoint Powershell Management Shell, by running Get-SPHelpCollection command.
- Run the command below to re-install the help file again:
Install-SPHelpCollection -LiteralPath ([Microsoft.SharePoint.Utilities.SPUtility]::GetGenericSetupPath("HCCab") + "\1033\Nintex.Workflow.HC.cab")
If a "Files do not exist" error occurs, contact Nntex Support to obtain a copy of the files, or check this file path in a working farm for the files: C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\HCCab\1033
