Can't download full High Sierra Installer

[app]

All I can get is the 19.9MB version

Here's what I'm doing: Open app store, click on Hight Sierra banner at top, click open, I'm presented with a window that says "To set up the installation of macOS High Sierra, click continue", I click continue, agree to license, click install, it says wait about 11 minutes, I wait about 11 minutes, then it says it's gonna reboot in 30 seconds or something like that, I quit the install, check my app folder and see the install package is 19.9MB. I've done this twice now.

If I then try to run the terminal command...

/Applications/"Install macOS High Sierra.app"/Contents/Resources/startosinstall --converttoapfs NO --agreetolicense

...I get the helper tool crashed error. After some searching it appears that the command might need the full installer to work.

Delete all copies of it, including those in the trash, external attached media, etc.
Then redownload from the Mac App Store.

I think this terminal command is what worked for me:

sudo softwareupdate --clear-catalog

Though I also just intuitively deleted the stub installer first, so can't really say if it was the terminal command or deleting the file that did the trick.
