You can't open Visio files in Visio Web Access even if Visio Viewer is installed
Symptoms
Consider the following scenario:
- You are running Internet Explorer.
- You have Visio Viewer installed on the computer.
- You try to open Microsoft Office Visio files in Visio Web Access.
In this scenario, when you click Open in Visio, you receive the following error message:
To open this document, your computer must be running a supported version of Microsoft Visio and a browser that supports opening files directly from Visio Web Access
Cause
This issue occurs because Visio Web Access invokes the client application by using the ms-visio:ofv|u|documenturl protocol, but Visio Viewer doesn't support or process this protocol.
Workaround
To work around this issue, install Visio desktop app.
Status
