Error with new install on Mac Mojave

Hello,

I just installed Photoshop Elements 2019 on a Mac running OS 10.14.2 and I when I click to launch the Photo Editor, I immediately get a dialog that says "There was an error opening this document.  The file is damaged and could not be repaired."  When I click the "OK" button, the editor launches but the dialog box comes back and keeps coming back and won't stay away.  This is a new install and this happened on the very first launch.  I force-quit the app and it just keeps happening.  I've tried holding down the command-shift-option keys while launching the editor to reset things, but this still happens.  Any ideas?

Thanks,

Ron
