Can't upgrade OS from High Sierra to Catalina on iMac 2015

I have a 2015 iMac running high sierra OS, but can't seem to upgrade to Catalina? Is there something I'm doing wrong. I can download it, but doesn't seem to start the installation.

The installation package will be in your Applications Folder. Try to run it from there.
