Hi @Andrey Lutsenko ,
What version of Office 2019 are you using?
As far as I know, the Administrative Template files (ADMX/ADML) for Office 2019 can work with Volume licensed versions of Office 2019, Project 2019, and Visio 2019.
I suggest you check if the Office 2019 version is correct.
I also suggest you download the latest version of Administrative Template files:
