Here are the Install notes from Majalis. I changed a bit to fit it for F95Zone. And added the notes with the *.
DESKTOP:
1. Download the appropriate ZIP file from the First Page. Options are Windows 64-bit(Win64), Mac, and Linux.
2. Extract the ZIP file to your preferred target installation folder, either using a program like 7zip or WinRAR, or using the native Windows and Mac archive extraction.
You should now have a folder in your target installation folder with a name like "Tales of Androgyny Win64" - inside of that folder should be a several files (e.g. TalesOfAndrogyny.jar, TalesOfAndrogyny.json) and a jre folder.
The structure differs depening on the version, but every version has some kind of application file, config.json, TalesOfAndrogyny.jar and a jre folder somewhere inside of it.
3. Navigate to and run TalesOfAndrogyny.exe on Windows, Tales of Androgyny Mac.app on Mac, or TalesOfAndrogyny on Linux (note that on Mac and Linux you may need to run chmod -x Tales of Androgyny Mac.app/TalesOfAndrogyny respectively). The game should launch, and the installation is complete!
