Trying to install High Sierra I get message: macOS could not be installed on your computer. The path/System/Installation/Packages/OSinstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again.
I have an iMac 2011. Tried force shutdown, but each time it reopens it is still trying to install the update and goes to the same message in a loop. Please can you advise what to do? Thanks
iMac 27", macOS 10.12

The installer should be sitting quietly in your Applications folder.
Verify you are not trying to use the very small stub installer some ~19 MB in size.
The full installer is 5-6 GB in size.
The stub is more of a place holder. If this is what you have delete the stub and empty the trash.
