Can't install on Mojave

I’ve been using SpamSieve on my Mac for years…and I am using Mojave too, but SpamSieve was already installed when I upgraded to Mojave.

I just purchased SpamSieve for my wife and attempted to install it on my her Mac (Mojave 10.14.6) for apple mail but I can’t get past the very first step in the installation regarding Full Disk Access. On that popup screen, the SpamSieve application is not shown and the add (+) button is greyed out.!

This is my first post on here, so I don’t know if the attached screen image below will work.

It looks like you need to click the lock icon to unlock the settings before you can click the + button. This is #2 in the more detailed instructions for Full Disk Access.

Thanks…sorry about that…sometimes I’m just a dumbass.
