Hi everyone! The company where I work has a full Creative Cloud Suite subscription. At both work and home I had a Mac Mini i7 (Late 2012) with Mojave 10.14.6 (I keep a 32/64 bit system so I can use older music software), but I never installed InDesign at home. In the company they bought a new Mac Mini M2, so I updated everything, operating system and programs! Instead, at home I sadly discovered that I can continue to use the apps I had installed (obviously without being able to update them, as it should be) but unfortunately I cannot install the previous version of InDesign (which as far as I know is compatible with my old Mini) because I have never installed any version of it. If there is a way, I haven't found it... Even though I have access to all apps. Is there a way to fix the problem? Thank you.
I believe that first you'll have to install Adobe's Creative Cloud application to "sign in" to your Creative Cloud account. As you've reported, you have the rights to install Creative Cloud apps (including InDesign) on two systems.
If the license you have on your work system system is applied to only one computer, and your employer lets you use your home system for the "second system" for your Creative Cloud license, you should be in good shape.
You've got a relatively narrow window for running Creative Cloud applications with your ol' Mac Mini on MacOS Mojave — I believe a range from CC 2019 to CC 2022. The ProDesignTools website offers legit downloads of current and older versions of Creative Cloud. You can find what you're looking for by going to this link and searching through the downloads section from the navigation bar.
