I have been playing WoW for 3 months and I downloaded questhelper at least a month ago.  The problem is.  I do NOT have the interface folder in my WoW folder and I cannot find it.  I have had two of my veteran playing friends to try and help me with no progress.  Any suggestions?  I would love to use some of the add ons. 

Heya Snaptypookie,

this might work when your using vista - C:\Users\Public\Games\World of Warcraft, i know when i had problems with Vista i had to find this file and i resolved the issue that way

Vista has a different way of installing AddOns for whatever reason...to reslove it, I used the Curse Client. I suggest that in case you download any more AddOns in the future ;)

If you read the stickies it explains the problem.
