File doesn't have .bat file when I extract?

[Shiuk21]

So I downloaded the latest file from the release page and extracted it. However, the launcher for Windows isn't in .bat file and instead only says launcher_WINDOWS. When I click on it it gives me this:
'java' is not recognized as an internal or external command,
operable program or batch file.
Press any key to exit...

that file is a .bat file but your file explorer just isn't showing the .bat on the end (it does this by default, you can change it by going to the "View" tab at the top of the file explorer and enabling "File name extensions")

As for the error you get, that means you don't have java installed, see here
