[Qgis-user] Open another instance of QGIS in Windows

[Kobben, Barend (UT-ITC)]

FYI, this does NOT work on Mac (OSX Sonoma 14.5) - it just focusses the already open QGIS instance....

That actually works. Yikes. Thats embarrassing :/ :) But Im 100% sure that has not always been the case (at least not at my PC); it used to just bring the already open instance into focus. Anyway, thanks for your super fast response and help :)

Hi Thomas

Yes. I have many instances opened concurrently with multiple projects. I too lost the file association with the project qgz a long time ago, due to me having multiple versions on my PC.

To achieve this, simply use the Windows (Start menu)/Mac (application menu), search for the QGIS application and version you want to use, then click to open a new instance.

I want two instances open at the same time, with each their project, so I can copy layer styling from one project to another.

Previously I did the following. Go to Windows Explorer, double click a .qgz file, and that project would open in another instance.

At some point, the file associations were lost, and if I double click the files, it asks what application to use, and QGIS is not even on the list. I think this happened after I installed using osgeo4w-installer, for "Just me" (though I'm not sure).

Anyway, is there anything I can do to open another instance?

Sincerely, Thomas
