Need to download Iguana 6.1.5, Iguana 6.2, or Chameleon for Windows?

Thanks to Colin McGrath, your wish is fulfilled.

Go to the downloads repository on GitHub.

Using GitHub for critical downloads like this is actually quite brilliant. The files are public, easy to find, and easy for other people to preserve.

If one copy disappears, anyone can fork or clone the repository and create another.

That is exactly how critical legacy software should be preserved: decentralized, transparent, and difficult to lose.

If you have any other old Iguana or Chameleon installers sitting around on a hard drive somewhere, please send them to me. I’d particularly love a standalone Chameleon installer, Iguana 5, and any other old versions we’re missing.

Sorry to rudely awaken everyone to this risk. But really, in 2026, Git is probably the only file-sharing model that makes sense for anything you genuinely don’t want to lose. I was trying to make this point to my staff but they blissfully preferred to make their own opaque file storage structures in platforms like Google Drive which are proprietary and completely at risk of losing data for ever.
