where can I get NCM 5.5.2?

I'm upgrading older version of NPM and associated modules.  I need to upgrade NCM 5.5.1 to 5.5.2 before I can install any NPM 10.x.  I've asked SW Support to make NCM 5.5.2 available for me to download, but they haven't responded yet.  I wondered if there was quicker way to find this older version?

Thanks
