I want to deploy a software (ArchiCAD 17) to a group of workstations where it isn't installed. So I try to create a dynamic group to collect these workstations with the following filter:
Product Name does not contain ArchiCAD
But the group contains a lot of workstations with ArchiCAD installed.

The other way works: To build a group with ArchiCAD installed, the filter
Product Name contains ArchiCAD
does it.

How would I build a group for workstations that have a software not installed?
