Hi @Paul, Satyendra ,
To help you better, I have something to confirm with you. What error did you encountered exactly? Could you please share here any specific error messages or screenshots?
Please note the below:
- Install only Workflow Manager 1.0 Refresh (CU2) using Web Platform Installer before you install any other components during the configuration. Restart the Web Platform Installer after to refresh the current installation status.
- You will need to install Azure Service Bus 1.1 and Workflow Manager 1.0 CU5 for SharePoint Server 2019.
- Make sure you meet all prerequisites for each component and Cumulative Update before the installation, including operating system, software requirements and SQL version.
Here is an article with detailed installation guidance for your reference: Configure SharePoint 2019 Workflow Manager - The Definitive Guide.
Also, you can Install Workflow Manager Offline. See if it lets you proceed.
