I can't open the forge installer "forge-1.19.3-44.1.0-mdk"

[BlackDragonsfr]

When I open my file "forge-1.19.3-44.1.0-mdk" (forge installer) my PC open an error window who say :

" java install failed;

cannot install java;

The following switches have errors: "C:Users\user\Downloads\forge-1.19.3-44.1.0-mdk.jar";.

Check that the commands are valid then try again. "

TY for your help

The MDK is an archive not a program. You unzip it. Or use

jar -xf file-name

which is the same thing as unzipping.

I don't understand how I can unzip it ?(When I unzip it with right click -> unzip , I get a folder not a program)

I found how to install forge (windows+r -> cmd -> java -jar forge-1.19.4-45.0.22-installer.jar) I don't understand why I can't install it when i juste click on it

Some zip managers like to take control of the .jar file extension away from Java.
Make sure you have Java installed and try running Jarfix once, then try the installer again.
