Dynamics 365 Finance Workflow Issue

Today, I was trying to open workflow configuration form in D365 Finance and getting below error.

Unable to install this application because an application with the same identity is already installed. To install this application, either modify the manifest version for this application or uninstall the preexisting application.

Usually this issue occurs, when you try to open workflow configuration form for different D365 environment and for previous environment, the component is already installed and running without any issues. I have two D365 Finance instances, on first instance the workflow configuration form is opening without any issues, but on the second one, I am getting above error. Below is the root cause and the solution for the above problem. Enjoy!

Cause

This issue occurs if the application was cached in the ClickOnce application cache. The application must be removed from the cache before you can successfully run it.

Solution

To clear the ClickOnce application cache, follow these steps:

1. Click Start, click Run, type cmd, and then click OK.
2. Type the following command, and then press Enter: rundll32 dfshim CleanOnlineAppCache
