The High Sierra download is available in the App Store, but after clicking on it the message is that this copy is damaged and can't be used for install. Why is it so hard to get this software?
Earlier Mac models
The "damaged" dialog is often due to an invalid or outdated certificate. Try creating a brand new User Account on that Mac with Admin privileges. Log in to that account, and try again.
It will be challenging to provide much more insight than that. All I can tell you is that it should be possible to install HS on that Mac.

Drag the installer app to the Trash and try downloading it from the App Store again by following the link below.
In a thread on macrumors.com, I read that downloading via firefox is the answer. So i tried that, and it worked. I have no idea why, but that was the answer. All installed, up and running. Thanks everyone.
I would suggest you run Disk Utility > First Aid on the drive from Recovery Mode.
Use macOS Recovery on an Intel-based Mac - Apple Support
It's possible there's an issue with the hard drive.
Just a comment, a 2010 Mac is seriously out of date, High Sierra is no longer supported, and many apps and sites will no longer work correctly. It may be time to think about a replacement.
Safe mode didn't work, couldn't find the installer in safe mode. I will try recovery mode. I'm fully aware it's long since time for a replacement. It's on the list, along with other expensive things I will need to pay for. I'm trying to ride this out for as long as I can. Thanks for your input, I appreciate it.
Thanks for your reply. I did that, downloaded it successfully from the app store, but it won't install. This is what I get.
Which Mac do you have and what version of macOS is it running?
Mid 2010, currently running on Sierra. I tried a restart of my computer, didn't work. I read to try installing from safe mode....
You're welcome. FWIW, "Install macOS High Sierra" would still be in the Applications folder in Safe Mode.
