Need back up my Logic, Ableton


New Member
Hello, I have been having problems with my computer and need to urgently clean the whole disk, otherwise it may crush and I could lose all of my software, including Logic, Ableton. I'd like to know, is it possible to back up the software somehow on to an external hard drive and after rebooting the computer, re-install it from that drive, without needing the original disk? If yes how to do that please.
Thank you
