1. Make sure you have Java 1.6 ((JRE) 6.0) Download Java software from Sun Microsystems & choose Offline installer.

2. Quote from one of the LW Programmers: "Vista tried to outsmart itself in dealing with folder permission problems. If a user tries to save a file to a location outside of their user directory, it will create a pseudo-directory somewhere else that only the running program will see. When that program runs, it will appear as if the file is in the expected location, but no other programs nor exploring from the desktop will see it.

If you're using Vista and want to see your files outside of LimeWire, you MUST make the save directory somewhere within your user directory."

3. Go to Desktop
Right Click On LimeWire Icon (or Installer)
Go to the Compatibility Tab
Go Down To Where It Says "Privilege Level"
Check the "Run this program as an administrator" box
Then Click "OK"
Open LimeWire
When Pop Up Asking For Security Permission Comes Up Click Allow
LimeWire Will Open and Vista Should Work
