Max 2025 install disappeared.

[Geoff K]

I'm not using Max 2026 yet, but I do have it installed and I just installed the latest versions of ForestPack and RailClone for it. Now iTooSoft products are no longer are available in Max 2025 (but they are in 2026). I uninstalled them and reinstalled the previous versions but they they still aren't showing up.

So I tried re-installing the new versions, this time making sure I installed it for both Max versions. But only Max 2026 is checkable (see attached screenshot). And when I do the same with the previous versions, I cannot specify any Max version at all.

Hi Geoffrey,

I'm sorry to hear you're experiencing trouble with it. We've run additional tests on multiple configurations here, and everything seems to be working correctly. Could you please double-check your system registry to ensure that the following key corresponding to 3ds Max 2025 is present?

HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\3dsMax\27.0

Thanks in advance for any further comments you can share about this issue with us or our user community, in case others run into similar troubles.

Best regards,

[Geoff K]

It looks like somehow 27.0 got removed (25.0, 26.0, and 28.0 are there though). I just tried to re-install Max 2025, but it would not proceed, saying that it is already installed. Do you know how I might be able to get it back? A week or so ago I removed Max 2024 and other associated things using a program called BC Uninstaller. I wonder if that had something to do with it.

Wow! Looks like ChatGPT knew how to modify the registry and fix the problem. I'm all good now.
