After wiping drive can't reinstall High Sierra (says corrupt installer)

I recently wiped a drive with High Sierra and accidentally factory reset it back to Mountain Lion. I gave the computer to someone else and now they can't update it to High Sierra. When they download it from the website it becomes corrupt and when they go to the app store it doesn't give the option to update it that way. I almost never have a problem installing MacOS in the past (Leopard was the last problem update I remember.) Any ideas on how I can fix this?

Mac mini, OS X El Capitan (10.11.6), Mountain Lion, trying to upgrade-HS

When I did the clean install I am pretty sure it got rid of all account info on the machine? So I didn't think I could log out if there was no longer any account info. All she got when I gave her the computer was a set up screen asking her to create a new account since at that time there were no accounts. All the info was transferred to a new iMac before wiping the Mini.

Just a thought, would it help to reformat the drive? After being on a drive with a newer OS would it help to use whatever format Moutain Lion was? I am also wonder if this question would make more sense to post in the Mountain Lion forums since that is the current OS of this computer?

I was able to fix this problem by searching for the High Sierra in the App Store instead of looking under updates where it usually is.

Did you log out of all your accounts on your old machine?
