So I tried to open a .jar file the other day and it told me i needed JDK, and so i got it and now the message does not come up. But when i open it is says it fails to open and the console tells me this:
Invalid or corrupt jarfile.
Is there any easy way to fix this?
Try re-downloading the file. Otherwise, contact the developer for help.
Which JDE did you install? Most likely you need one from Oracle unless this is for a machine requiring Apple's old JDE: Download Java for OS X 2017-001.
i got my JDK from Oracle but every single .jar file does not work to open... most games that i use dont need me to open files but this one needs me to open it to get it started/installed. I have the Java from Oracle and the versions is 12.0.1. If it is important i am running El Capitan
Ok.... so it turns out that when i moved from my old PC to my new one all of the files got corrupted so all i have to do is redownload them... Thanks!
I cant open .Jar files
