itch.io

Some game developers still use non free license archive types to compress their game distributions, so the app cannot open it. You have to manually download the game archive in web browser and extract with 3rd party program like 7zip.

Hi there :)

As Hildunn stated, you can download and extract the game archive manually through your browser. The Windows / Mac readme's also recommend doing this, as it is probably the easiest way.

That being said, there is also a workaround to guide itch.io past the decompression error. I made a post describing this process about one month ago, it should still be functional:

Hope that helps!
