I am trying to update my OS to Catalina from Yosemite. I have made my backup and am trying to now access the old installer and it says I need to choose an app to open the link...I tried iTunes and it said it was no longer available in the US store. I tried the App Store app and nothing ever came up. Any suggestions on what app I need to use? Thank you!

Make Time Machine Backup is very useful and can be used to Revert to Previous Working macOS
Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.
Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.
Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation
