Open 2 Visio diagrams in different windows [closed]

I would like to know if I can open 2 different diagrams using MS Visio and each diagram have its own window. I've tried in several ways, but I always end up with 1 Visio window . I'm using a triple monitor setup and I'd like to put one diagram to each side of my main monitor. []'s André Casteliano PS: I'm using Visio 2007 here.

Why was this question not migrated to Super User? There's now another question asking the same thing which actually points to and uses the correct answer from here instead. (not the accepted answer, the registry answer.) Closure brigade strikes again I guess. superuser.com/questions/679860/…

@MarkAllen Yeah I don't understand why so many questions get closed instead of being moved. This happens most of the time by far. It adds more noise to the SE network and waste people's time.

This allows you to open two or more instances of Visio so that you can view different Visio docs at the same time without going through the process to stretch the Visio window across two screens. I found this to be a simpler method and a bit easier to manipulate. If it doesn't work on your first try recheck the registry setting. It changed back on me a couple of times before it took.

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

1. Open Microsoft Visio.
2. Go to Tools -> Options -> Advanced or File -> Options -> Advanced in newer versions.
3. Check the Put all settings in Windows Registry option.
4. Close Microsoft Visio
5. Run Registry Editor (regedit).
6. Navigate to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Visio\Application\
   Note: The value 12.0 in the key can be different. (i.e: for Visio 2010: 14.0 , Visio 2019: 16.0 )
7. In the right pane, right click on SingleInstanceFileOpen , and then select Modify. Update the value of SingleInstanceFileOpen from 1 to 0

If the value SingleInstanceFileOpen doesn't exist, it can be created as a type REG_SZ.
