While searching 'All Computers' in the GSS console (simple search) for computers with 'Application Name' > 'contains', with a value matching the name of the application, some applications return no computer results even though the application is installed on those machines
Ghost Solution Suite 3.3 RU11
The computer search pulls application inventory from eXpress DB table dbo.application
dbo.application lists applications 'name' as MSI product GUID for applications installed with .MSI (Microsoft Software Installer)
So, searching by the actual application name will not return results for software installed via .msi installer unless you search by MSI product GUID
This issue has been addressed in GSS 3.3 RU12 release.
As a workaround, searching by Application Description for applications installed via .msi should return accurate results.
