How to fix having to launch ClickOnce manually

Question

Hi,

For the last week and a half, users in our org have sporadically started encountering issues with launching Deltek Vision, an application we access with a shortcut that opens as a .Application in Edge via ClickOnce. The prompt to open the file will appear in Edge but nothing happens after you click Open. The workaround we have for now is manually launching dfsvc in C:\Windows\Microsoft.NET\Framework64\v4.0.30319, which appears to run the ClickOnce service/process when checked in Task Manager.

How can this be permanently resolved though?

Hello,

According to the discription, you have issues when launching Deltek Vision via ClickOnce in Edge.

Try below methods:

1. Open edge and enter:

edge://flags

Enable ClickOnceSupport

Then restart edge

2 . On the vision splash screen that displays when you launch Vision, click Do not load Startup Application, then log on to Vision.

3. Check if there is update for Deltek Vision and Edge, search if there is any known issue.
4. If above steps still donot work, consider contact Deltek support for further help.

Best regards,

Molly
