Install MSI via GPO and customized .mst file

Hi.
I’m trying to deploy Nextcloud client MSI via GPO policy. I made a customization MST file with Master Packager which disables update notifications, the policy is being applied to computers but apparently the msi still shows the wizard, so install is not fully automated.

I checked the options in the guide and doesn’t tell anything specific about not showing the wizard. Did I miss something?

Thanks
