[Topic already exist]: key for step 7 v5.7 on windows 11

[ladderlogic]

Dear Team,
I need your help, I'm having course on how to program plc. unfortunately the instructor is using Simatic step 7 v5.7.
and I'm trying to install it on my window11. it requests license key. when I checked it out. its extremely expensive.

I just need this program to train myself. thus I would highly appreciated if i could or know the way to install it on my computer without paying.
