How to use Adobe program after school adobe support is cut off

Hello, I used an Adobe program for about 2 years that can be used for free if I connect to the school wifi network.

I want to install a new Adobe program because Adobe support has been cut off at school. In this case, do I have to format my laptop and install a new Adobe? Can't I just subscribe and install Adobe? I don't want to format my laptop...

 Is there a separate function to delete Adobe programs from Adobe itself?
