Can I share apps created in Qlik Sense Desktop?
Yes. There are no limitations in sharing applications between different installations/instances of Qlik Sense Desktop.
Note: QVF files need to be located in a specific folder - C:\Users\USERNAME\Documents\Qlik\Sense\Apps
The folder cannot be a shared drive folder or a shared folder. Once a qvf is open, it is modified so other instances of the Desktop cannot open it or copy it.
