You need Java to experience Open3DHouse™. If you don't have it already don’t worry, it should install automatically. Just follow the instructions.

I need to download all the Open3DHouse™ definitions and furniture; I hope your internet connection is good. If not, be patient, I will finish as quickly. Promise.

Is your computer good enough to play new computer games? If it is, then your experience with Open3DHouse™ will be smooth. If not, it may be a little jerky, but you’ll still be able to use it.
