I tried Barney-15's advice on upgrading to macOS Mojave. But it didn't work, even after trying it numerous times. The message I received, just before the iMac was to restart was the following:

An error occurred while preparing the installation. Try running this application again.

In one of the earlier attempts an 'incompatibility' installer was run. But that didn't solve the problem either.

I will offer some thoughts, assuming that your Mac is one that can accept Mojave. Sometimes a downloaded installer file can become corrupted. We keep trying to install it and it never works, but we have no way of knowing it was corrupted. Better to drag the installer to the trash, empty it and try a new download. That said, corruption is most likely to happen when we are downloading it via wifi. A lot of data is being downloaded and often the wifi can't handle it. Multiple attempts may be needed to get a clean download. If you can use a wired ethernet connection, it is far better, even if you have to temporarily move your computer to do it. Good luck.
