4004 was a preview version.
See the original post for it here ... https://archicad-talk.graphisoft.com/vi ... 10&t=69014
Note the quote form Laszlo in the first post.
Even if you follow the link in Karl's post, it will take you to the new build 4006.
The preview version is no longer available or needed as it has been superseded with 4006.
You will be best to update your company to 4006 as well.
