I double click on the .jar file and get this image:
Under review
Can you open a command prompt (cmd.exe) and run "java -jar [your jar file]"?  Make sure you first "cd" into the directory where you saved the jar file.

This will show me what the problem is.
C:\Users\user\Downloads>java -jar masterpassword-gui.jar

When did you download this JAR?
Can you try re-downloading the app now and trying again?
