An unknown error has occurred. The form template has been published to the server but it can only be opened in InfoPath filler

Recently I was getting the below error while publishing an InfoPath form in SharePoint 2013, the error coming was: An unknown error has occurred. The form template has been published to the server but it can only be opened in InfoPath Filler. The InfoPath form I was using inside a workflow in SharePoint 2013. But I was not able to publish.

After searching for a solution, I got to know that we need “Desktop Experience” feature.

Open Server Manager in the server. Click on “Add Roles And Features” -> Then click on Next till you reach Features section. Here expand “User Interfaces and Infrastructure” and check the checkbox like below. Then follow the next steps and install it. If required restart once.
