When we tried to access Minecraft Forge Forum, there is a thread about it. Someone also found a problem where he could not open the Forge Installer. To solve this, he tried to uninstall Java completely and then he reinstalled it. He also tried to uninstall and reinstall JRE (Java Runtime Environment) separately from the regular Java program. Another thing that he did is moving the files from another computer. Changing file extensions and also a program called Jarfix as we explained earlier are also done by him. But, it did not help him. Another player suggested him to download the Windows Installer, not the plain Installer and he also suggested not to open the Java file by clicking it twice but open the Command Prompt and go to the file directory. After that, run the Java file through here. The , in the Command Prompt, you have to type: java -[YOUR JAVA FILE NAME] . jar [optional modifiers here].
Some others suggested him not to use the newest version of Java but use the old one but of course do not use the version which is too old. Well, you can try any methods to fix this issue. But, you may be able to try to restart your device and if it does not work, you can try to download Jarfix as we explained above because usually this method should be able to fix this issue.
