Hi, although Peter has already answered your question, I would like to post it again for someone who is looking for this link.
Please use this link to download the latest FEFLOW 7.4 version:
https://www.mikepoweredbydhi.com/download/mike-2021/feflow?ref={2BC171FE-7AFA-44A0-9BF8-BC48CEAC27A8}
When you start to install the package, there is one option called [b]FELOW Demo Data[/b].
The package also includes example animations, demo tutorial videos, and third-party software PEST.
By default, the tutorial files will be saved under C:\Users\Public\Documents\DHI FEFLOW 7.4\demo\exercise
