Can the Beta version and Legacy version of Presenter co-exist?

Can the Beta version and Legacy version of Presenter co-exist - meaning can I install both and run in parallel?

I have both versions installed on an apple mac but I notice I can only open one version at a time.

On Windows, tell the beta installer that you want to install the beta just for you. The the legacy install stays on your computer. The start menu and taskbar shortcuts are changed to the beta, but any desktop shortcuts are unchanged, so that's how to get to the legacy version after installing the beta. If you tell the beta installer to install for everyone who uses the computer, it removes the legacy version from your computer.

And it looks like you can't have both running at the same time. I tried loading 2025 first and loading 2026 first. Both situations didn't do anything when I tried to load the other version, regardless of what shortcut I used.
