Can't download macOS High Sierra once again I've macOS High Sierra 10.13.6 (17G8023) installed. The icon of the app, "Installation of macOS High Sierra" is available in /Application:

ls -al /Applications | grep macOS
drwxr-xr-x@   4 root   wheel    136  8 июн  2018 Установка macOS High Sierra.appdownload


("Установка" means "Installation" in my localized OS X version)

The app start should download installer according to my expectation. But it doesn't. On the other hand "Installation of macOS High Sierra" is not included in the list of my purchased application in App Store. I can see previous versions in this list (OS X El Capitan, OS X Yosemite etc.), but not macOS High Sierra and macOS Sierra.

I also tried to find "Installation of macOS High Sierra" using App Store's search.

Both macOS High Sierra and macOS Sierra are absent in the results. Could you please advise how to download macOS High Sierra installation application?

The installer is downloaded in /Applications directory and is typically around 6GB in size. If needed, delete the installer currently present in /Applications directory.
