Uninstalling previous Workflow Manager (Classic) products
If any ArcGIS products are installed on your machine and are earlier releases to 10.8.1, they need to be updated to 10.8.1 before proceeding with the ArcGIS Workflow Manager (Classic) Desktop setup. The ArcGIS 10.8.1 Workflow Manager (Classic) setup package is designed to detect and upgrade an existing installation of ArcGIS Workflow Manager (Classic) Desktop.
Esri strongly recommends that all sample and third-party extensions or plugs-ins be uninstalled before installing a newer release of ArcGIS. Remove these from your computer before uninstalling ArcGIS products. Contact the distributor or manufacturer to confirm that they are supported with ArcGIS 10.8.1. If they are, you can install them again after installing ArcGIS 10.8.1.
The Workflow Manager (Classic) setup will terminate and display a dialog box if conflicting releases of these products exist on your machine. If so, you must uninstall each of them and run the ArcGIS Desktop setup again to proceed with your installation.
As long as all the installed products are for the 10.8.1 release, they can coexist on your computer without conflict.
If both ArcGIS Workflow Manager (Classic) Desktop and ArcGIS Workflow Manager (Classic) Server are installed on a system, they must be uninstalled in a specific order. Workflow Manager (Classic) for Desktop must be uninstalled before Workflow Manager (Classic) for Server.
Always use Add/Remove Programs from the Windows control panel to uninstall these products.
