That isnt your EQ2 folder thats the folder for the launch pad patcher. In EQ2 the patcher is a separate program. You see a skin folder there because the launcher uses the same interface system.
You need to find your Everquest II folder and you can do that by right clicking on the EQ2 Icon you use to load EQ2 and choosing properties. The Target: will show you the correct path.
Then just follow the directions in the sticky thread and you should be all set.
