Double-click on 2026 project opens C4D2025

[entry-newspaper]

I just installed C4D 2026. It's on a machine with 2025 and 2023.
Oddly, when I double-clicked on a test project which had just been saved from 2026 (with C4D 2026 already being open, no less!) 2025 opened that file, instead.

Any idea why that would occur? This is on my M1 Ultra, running 15.7 Sequoia.

Hi entry-newspaper,

On a Mac, use the CMD + I to get the information about the file you like to open, then set the application you like to use, and if that is needed for all, use the change all button.

If that is only wanted for a single file, use the Right-Mouse-Click to get the Open With option. If 2026 is not in teh list so far, scroll down and use "Other…". It should be in that list after this first time.

All the best

Thanks, Dr. Sassi. I'll likely do just that. But doesn't it seem odd, that it would open an older version? I've never before seen that. No idea if that's some glitch in Cinema, or more likely the Mac OS?

Thank you for the reply, entry-newspaper.

I have seen it from time to time, no idea what it causes, but since I do not use double-click a lot (I work mostly from a tablet), I drag the files on the icon in the dock. So, I'm not the one with the most experience with double-clicks anymore. Besides, if the file is a fake file, it might open something else (Yes, pure neurotic, based on too much security training that I have to take.

All the best
