问题
I work with NetBeans 7.4 + Java Update 45 installed on Windows 8.1. I've tried to get to the Java Control Panel, by using the Windows search charm. This does, indeed, lead me to a java icon for the Java Control panel. However, when I click on the icon, something flashes by and then nothing. Does anyone know a work around?
回答1:
Try running
C:\Program Files (x86)\Java\jdk1.7.0_45\jre\bin\javacpl.exe
if using 32-bit Java, or
C:\Program Files\Java\jdk1.7.0_45\jre\bin\javacpl.exe
if using 64-bit Java. You'll need to run them as administrator for the settings to take effect.
