Certain apps don´t appear in the CC app and cannot be downloaded (Premiere, Audition..)

Hello,

I manage the computer room / media lab for a university and have trouble installing / running certain Adobe apps, namely Premiere and Audition. It´s a full CC license for education institutions.

Recently any Adobe app would close immediately after launch. For reinstallation purposes, I uninstalled Premiere to check if that would fix the problem - unfortunately, Premiere has completely vanished. It is uninstalled from the computer and doesn´t appear on the CC management app anywhere. When I try to download it via the Adobe website, it redirects to the CC app where it still cannot be found. It´s the same problem when I try to install it locally (e.g. using an installation file from a different website).

I have tried several things:

- updated windows (we have Windows 10 Education; unfortunately the computers lack a tpm component, so they cannot be updated to Windows 11)

- updated CC, uninstalled and re-installed it

- checked for compatibility mode issues (there were none)

- googled a lot without success

- checked whether the computers fulfill the system requirements via Adobe´s website (they do, at least according to the green check mark)

I managed to solve the problem of the installed apps crashing instantly, but cannot solve the problem of Premiere and Audition not appearing anywhere / being unable to download them.

This is only an issue with the two computers in the lab. On my own office computer, it works just fine.

Both computers are 64 bit, Windows 10 Education and maybe 3-4 years old.

Any help / advice would be appreciated. Thanks!
