Updating iWork
I have iWork08, but my MacOS Mojave. I no longer can get iWork programmes such as Keynote to work. I have downloaded the new iWork 9.3 and this says it cannot open because it cannot find iWork 09. I have managed to update Pages and this functions well. My Numbers programme also functions well. How can I get Keynote to work?
