Installing Lightroom 5 on a Mac without DVD-drive

[Outsourcing]

Hey, I found an old DVD with Adobe Photoshop Lightroom 5, which I got when I bought my camera.
Unfortunately I can't put it into my new Mac. When I tried to copy the installation files from a Windows computer to my Mac, I didn't see any .dmg or similar.
Unfortunately, I could not find a file to download on the Internet. What can I do to use the software on my Mac?

What is your MACOS version?

Try copying the DVD files to a USB flash drive that has been formatted to exFAT as described at the below link:

Just a couple of knowns you should be aware of. First, if your new Mac is running macOS 15 Catalina it will be impossible to install Lightroom 5 even if you were to download the installer online since it is a 32 bit and Catalina will only work with 64 Bit systems. Second does the disk have the 16 numeric serial number? Did you register the product or install it on another computer?
