Re: Launch multiple instances of SweetHome3D?
I added the com.eteks.sweethome3d.singleInstance system property in Sweet Home 3D 6.5 to make each launch of the application run in a separated process when set to false.

To use this property, add the line
-Dcom.eteks.sweethome3d.singleInstance=false
to a file named SweetHome3D.l4j.ini and stored in Sweet Home 3D installation folder.


I too would like to be able to run two instances of your excellent program but I cannot find any file named: "SweetHome3D.l4j.ini" in the Sweet Home 3D installation folder (or anywhere else on my computer).

I am running version 7.5 of the program on a Windows 10 PC.

Does the facility only exist for Linux users or can you tell me how to do it in Windows 10 please?

Thank you, &
Kind Regards.
