The old store is no more! Marten 1.6.5 for macOS is available as a free download. It should be understood that the Marten IDE is a 32 bit Intel application and will run on macOS Intel platforms up to and including macOS Mojave Version 10.14.6. It will not run on later versions of macOS as those are strictly 64 bit only and do not support 32 bit applications.
