Use the Linux link, and run this from within WSL.
I can see the problem; in our official docs we don't clearly say that we will be using Windows Subsystem for Linux because we don't support Windows natively.
So after going to the install instructions for miniconda, you select Windows (of course!) but it's a trap.
Because Qiime2 does not run on Windows.
Qiime2 does run on Windows Subsystem for Linux, which is Linux.
So only option that will work, counterintuitively, is Linux.
I'm sorry this process has taken a while. Now that you know to always use WSL, I think we are on the right track!
Thank you for your patience.
