The link for Mojave (want to stay with 32 bit) on Apple's support page, after clicking in Apps store says "This copy of the Install macOS Mojave application is damaged, and can‘t be used to install macOS." Where can I find an undamaged disk to upgrade from Sierra? I do not want current OS since I use many 32 bit programs and don't want to lose the readability.

Did you follow the steps mentioned in this article, to download the installer?
You will have to open the article in Safari, otherwise the links will not work correctly.

Did you restart after trashing the old one?
Choose Applications from the Finder's Go menu, throw the existing installer away, and download it again.
The point about only opening the links in Safari no longer applies.

I threw out the existing installer and this time used Firefox and got Mohave to totally download. However, I got the same error message that it was damaged. Wonder if the link no longer works?
