Can't launch the installer

[EricRRV]

I have the lastest version of java for windows 8 and tried right clic the jar file then "open with" and select java.

Also tried the jarfix and doesn't work.

I downloaded some forge versions to be sure it's not a bug or something but nothing works.

 

Help please

Use the .exe launcher.

It solved my problem for the lastest versions of minecraft...

 

But what if I want to play with mods in older versions which doesn't have an .exe launcher?

The installer .exe dates back to the latest version of 1.6.4.

 

Tip: If you really wanna execute a .jar file and you can't by simply double-click on it and the jarfix doesn't work, you can do that via command line:

java -jar "C:\path\to\my\JarFile.jar

If it cannot recognize java as a command, add the java executable to your PATH environment variable and try again: https://www.java.com/en/download/help/path.xml

 

We can't help you any further on that, though, since we only support the Forge versions for the latest Minecraft version(s) (at the time of this post for 1.8 and 1.7.10)
