Downloaders for earlier versions of Photoshop, Illustrator and InDesign (with Postscript support)

With Adobe having ceased support for Postscript fonts in recent years, we have maintained versions of Photoshop 2021 and Illustrator and InDesign 2022 on our designers' computers, so that historic files could be opened and edited. Until recently, it has always been possible to install these earlier versions of the apps via the Creative Cloud Desktop app by clicking on the three dots and selecting "Other Versions".

Unfortunately, it has recently come to light that this option has now been limited to just versions from the past two years, which means that the specific versions we need are no longer accessible.

I have contacted Adobe directly to ask whether they may be able to supply me with download links for the standalone installers, so that we can keep these on file for future use, but they have been particularly unhelpful in this regard, saying that I'd have to see if something could be found via this Community site, so here I am...

Can anybody help?

For reference, I am looking for the Mac OS installers for the last versions of Photoshop, Illustrator and InDesign that support Postscript fonts.

Thanks!
