MacOS – Install macOS High Sierra won’t Delete

high sierramacos

I am kinda running out of room on my Mac, and in System Information (comes up when I click "manage" in "storage" of "About This Mac"), I saw that "Install macOS High Sierra" was taking 5.21 GB.

I thought that deleting it would solve my storage problem for now. I had it because I recently updated my mac to macOS Mojave 10.14 which I love, but that dang file won't go away. I click it, then delete. Then, I get a confirmation, "are you sure" and such.

After clicking "delete" I enter my password for permission because its an "application change". Then, the top tab goes away and nothing happens. I've been thought this process a few dozen times and I have no idea why nothing happens.

How can I get rid of the file and reclaim the space?

It’s in /Applications but has a slashed circle symbol over it.
