I managed to get it working, thanks to WSL. Watch the video and read the description

Solution:

Install WSL almalinux on Windows 11. Then install flathub from terminal. Then install strawberry flatpak. (Tried, it works.)

Install WSL fedora on Windows 11 (not recommended, not official)
2.1. on fedora OS download strawberry from terminal, install.
2.2. install flathub from terminal. Then install strawberry flatpak (I haven't tried it).

This is not a bug. It's just about information that is not on the github page and not on the wiki page. I didn't manage to download it on Windows 11, so I installed WSL, I installed Almalinux.
I will install Strawberry on Almalinux 9 Cli OS. I don't know if Strawberry is available in the store. I can't open the GUI store because it's Cli. I want to install it (not compile) but I don't know the installation code.
"sudo dnf install strawberry" Is it true?
There is no information about this on your github page and wiki page. Can you add the information?

And

It's listed as free on Alternativeto. The download page asks for a "tip". Is it paid for Windows? Is the information in Alternativeto wrong? When I select free and Windows from the filters, Strawberry is listed. Should Alternativeto be corrected?
Free for Windows or $20?
If it is free, I couldn't find where and how to download it. Can you help me?

Expected behavior
If it is paid, the filter in alternativeto should be edited.
If it is free, it should be explained how and where we can download it.

System Information:

Operating system: Windows 11 Pro x64 24H2
Strawberry Version: latest
