Not installing online meaning just that, not downlding the information as you're installing. That is what online installers do. Better to downld the installer to your computer, then install. So the installer is not waiting for extra information/data whilst in the process of installing. BTW you're better off with Java 1.5 for LW 4.10

If you go to the bottom of the page here Fixes for Limewire you'll find a sample image that shows how to delete your LW preferences folder. If you've never used a version earlier than 4.10 then the LW prefs folder will be called limewire & in a hidden folder. If you have used an earlier version of LW, then the prefs folder will be called .limewire

If your computer is very slow, then a reboot before deleting the preferences folder might be needed.

It might also be an idea to purge your incomplete files. Find your incomplete folder; use the computer search function, type in incomplete, then open the incomplete folder & send all items to the recycle bin.

Then try opening LW again.
