Mac OS Sequoia 15.6 can't install any Canon software using this installer. It comes down to dirty coding, while debugging and looking through the log report the issue is plain and simple. Canon developers have two instances trying to do the same function at the same time, they have both instances located in two different paths.

Mac Debug / Install Error:
Class CmdUtil is implemented in both /private/var/folders/yg/500ny9b515ncyqn9n7b1rdr00000gn/T/CanonOFI_TEMP/Data/Software/Install/UniversalInstaller.app/Contents/MacOS/UniversalInstaller (0x10874b008)

This will cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

Come on CANON this is a 2 min fix! Billions of dollars made off the backs of your customers and you can not fix an installer?
Do I have to make a post showing others how to patch the lines of code in your dirty coding so they can run these installers on their Mac computers? GET IT TOGETHER CANON

Your complaint is the first that I have heard of the installation process crashing. How often do you reboot your computer?
Apple writes the installation code. Software developers like Canon create a GUI for it.

I have altered the canon installer line code locally and the install is 100%. Native down loaded installers crash with Sequoia 15.6.

What Canon software are you talking about?
What Canon equipment are you using?

I just installed DPP on a MacBook Air w/macOS 15.6 without incident. Whatever problem you may be having doesn't seem to be universal.
