Can't open two instances of Visio 2013

Question

I've faced with strange behavior of Visio. I'm opening two documents, but there is still one running application. And I can't move one, to another display. This is kind of annoying thing, and it slows my productivity. Is there any solutions, or it is known issue?

P.S. I'm using Windows 8.1

Answer 1

Actually I've followed steps described here.

To implement the new behavior, follow the following registry trick:

1. Open Microsoft Visio.
2. Go to Tools -> Options -> Advanced.
3. Check the Put all settings in Windows Registry option.
4. Run Registry Editor (regedit).

5. Navigate to the following registry key:
   
   HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Visio\Application\

6. In the right pane, right click on SingleInstanceFileOpen, and then select Modify. Update the value of SingleInstanceFileOpen from 1 to 0.

But key was missing on my machine, so I've just added it and rebooted machine. Now it seems work.

Answer 2

Open one instance of Visio 2013 and a icon will appear in the task bar. Now hold Shift and click on the Visio taskbar icon (or middle-click on the icon). A new instance will open. This works for all programs not just Visio 2013.
