.JAR Files and Issues with Minecraft Mods

[northeastgamer]

Right, so I recently installed optifine on my PC to help boost minecraft performance. it was fairly simple. I downloaded the .JAR, clicked open, and selected install. However, when I try to do this on my laptop from the exact same download link it will not run and yes, my laptop has Java. I even tried reinstalling it. Here are some key differences I noticed.

 

1. On my pc the downloaded file had a java style thumbnail, while the thumbnail on the laptop was just a piece of paper with the corner bent.

 

2. When I hit open on my pc it showed the install menu for optifine, while on my laptop it just flashed the command prompt for a split second.

 

I feel like the solution will be stupidly simple, but I cannot seem to figure it out. Any ideas?

 Unfortunately I have tried this, but it still will not work.

The fact that it was a black icon means windows did not know what a .JAR file was on your laptop.

1. Check java is installed, both 64 and 32 bit and check it in internet explorer.

2. go into default programs and associate the .JAR type with java.

3. if nessesary install extra java stuff like JRE

the first step is to not use optifine.

 

at some point the dev drunk the wrong kind of tea, and honestly unless things have improved the mod does more bad than it does good.

It worked! I told you it would be something stupidly simple.

1. open command prompt

2. type in path to java.exe

3. type in " -Xmx1g -jar "

4. type in path to your *.jar file

end result should look something like this:

C:\jdk\jre\bin\java.exe -Xmx1g -jar F:\HWBot\hwbotprime-0.8.3.jar

I had to change the default program for .JAR files.
