Archipack Tools Location I created a simple wall in blender using Archipack but any time I change it, height etc, it deletes all my windows,  A little reading indicates that I must make it "safe to edit".

"In order to prevent any parameter edit and get a “safe to edit by hand” non-archipack aware mesh, use either “selected” or “all” found in Archipack Tools -> Kill parameters."

But nowhere does anything say WHERE the Archipack Tools are to find this option.

It's not in my right-click where I managed to get Loops tools to show up once.  It's not down the side with the Archipack - all I get there is the Material and the wall itself with its details.

(The answer below says that it should be in the side menu accessible by pressing N.  I don't have "Tools".  Extended Tools is from a Modeling Cloth add-on.)
In free version you must remove archipack parameters using python console.
Take a look at custom properties in mesh tab, you'll find the name of the property to remove. (for wall it is archipack_wall2)

Select your wall, then in python interactive console, enter 

C.active_object.data.archipack_wall2.clear()
