Loading the installation file
 

I have a problem when I load the installation file, they said error! "can't initialize plugings directories" someone can help me with this problem?

Is it the installer or when you 1st open the program?

If it's the installer, then try another installer. In fact with this one there's no installation, you simply unzip it & use: see about it here Unzip it & use

Sounds like a bad Java installation. Uninstall all Java version and reboot. Then download the newest version using the JRE offline installer from here:

Install it and reboot again. Then reinstall LW.
