The real question here is what are you trying to do?
Still, this. ^
What, specifically, do you need AceGUI for?
For some reason, there's a major misconception by novice AddOn authors that AceGUI will make frame creation and manipulation easier - this isn't actually what it was designed for, and it is actually easier to use the default UI API for those things.
If this isn't your intent, then the original question still stands. Nobody can answer you with any real knowledge unless we know exactly what you're trying to do with AceGUI and why you think this is the proper tool.
