[Zope] problem with read only zope. Does not load some products (Archetypes)

Hi there, I am creating a CD with the copy of a site. The idea is, that the CD could be used in places where there is no internet access. No my problem is, that on of the products (Archetypes) is not initialized correctly at startup. And therefor all dependent products are not initialized neither. After Zope has been loaded, I can go to the control panel and load archetypes and the dependent products manually. Unfortunately this is not something I can ask the users "in the field" to do. Has anybody an Idea what I could do, to have Archetypes loaded the "official" way. thanks Robert
