Cannot install OS Mac High Sierra

I downloaded High Sierra from the Mac store and received the following error message during the installation process:

The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged. Quit the installer to restart your computer and try again.

I don't know how to quit the installer since I am stuck on this screen. I have rebooted several times, only to come back to this screen/error display. I tried a Safe Mode restart but have been stuck in it for over an hour.

Any help would be appreciated. Thanks.

macOS Sierra (10.12.6)

Mine gave the same error message. After rebooting a few times and getting to the same spot, I found a post that said to hold down the shift key (Boot into safe mode) to get past it. I did this and the progress bar froze at about 90%. I hard rebooted it after about 10 minutes of inactivity and tried it again. The second/or third time of trying to boot into safe mode finally progressed. A different looking progress bar appeared followed by the normal progress bar. After that a progress bar appeared telling me that Installation was occurring. ~40minutes later everything was installed and seems to be working fine.

I have no idea if this impacted anything, but while I was on the first screen with the original error message, I clicked the menu bar at the top and connected to my wireless network. Like I said, I have NO IDEA if this impacted anything, but it was something that I did and my system completed the installation successfully.

I tried to install macOS high sierra on my MacBook Air, but after the reboot I find this blinking image (a question mark in a file log).

Could you help me?

As long as the external drive has enough space to cover whatever you’ve got on your Mac hard drive, you’ll be fine.

As long as you follow the steps previously posted, you’ll be fine. I didn’t lose anything

I guess I'm one of the few people that this did not work for.

Apple needs to step up and figure this out... it's obviously a wide spread problem.

If you set the startup disk to the physical boot disk there should be no need to run First Aid Repair.
