I downloaded the latest version EncryptMyPack, and i have the latest version of Java installed, but if i double click on the downloaded jar, it gives me this error:

Please help me

Open a terminal window and navigate to the folder containing the EncryptMyPack-2.0.1-shaded.jar file. Then enter the command java -jar EncryptMyPack-2.0.1-shaded.jar

Already tried and the error still appears

Check if Java is installed by entering the command java -version in the same terminal

You need Java version 21+, but you have Java version 17.

But how, yesterday i updated Java to the latest version?

[Galyckyj]

This happens when you have an old version of Java and you downloaded a new one, but it did not update the paths in the environment variables. You need to update them yourself.

Do you know how i can do it please?

[Galyckyj]

So, tell me where you installed the new version of Java?
