Hi @Asma Sultana ,
Do you mean you want to open Visio files in separate windows?
Please try this method:
•Open Microsoft Visio from the start menu.
•Go to File > Options > Advanced. Scroll down to the General section and enable an option called "Put all settings in Windows registry". Save changes and close Visio.
•Open Windows registry editor (regedit.exe), navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Visio\Application and modify a String type entry called SingleInstanceFileOpen. All you need to do is change the value from 1 to 0.
•Close the registry editor and try to open couple of Microsoft Vision documents by double clicking on them. They should now open in individual windows.
