DUA 2.x requires creation of MST transform data, that can be deployed with the main MSI package using GPO. This explained in DUA User Guide document here:
https://support.quest.com/technical-documents/on-demand-migration/current/desktop-update-agent-user-guide#TOPIC-1864265
To prove that, MSI with MST file can be installed manually using the following command:
msiexec /I "<DUA_MSI_file>" TRANSFORMS="<DUA_MST_file>"
Where DUA_MSI/MST_file are names of MSI and MST files in the current folder or full path can be provided instead.
