i1 Profiler

Forgive me I'm only a very occasional poster. I was wondering if anyone can point me at a working download link for an old version of i1 profiler for Mac - v3.3.0, ideally, or earlier. The link on the XRite site doesn't work. I'm trying to profile a monitor on an old Mac running macOS 10.13.6 and I stupidly let my very old version of the software (1.6.3) update itself when prompted on opening. So it's installed the latest version, which won't run and just copying the old version back doesn't work (as might be expected). Also any tips on uninstalling the current version first. Many thanks in advance. Tony
