Installing OZ Virtual
What do I need to use OZ Virtual?
To use OZ Virtual, you need a PC with a Pentium
processor of at least 90MHz. You must run Windows 95 or NT 4.0.
A sound card and speakers will also let you experience the high-quality
music in OZ worlds. A microphone will let you enjoy voice chat
with other avatars. OZ takes up at least 20MB of disk space (OZ
Virtual is about 4.5MB; ActiveX, DirectSound, and Java Virtual
Machine will take the rest but users of Microsoft Internet Explorer
will already have ActiveX and Java Virtual Machine). Note also
that you will consume more disk space as you travel and download
new OZ VRML worlds from the Internet.
Software and connection requirements
The OZ Virtual client software is all you
need. This software communicates with an OZ server network, allowing
you to explore worlds with other people. OZ worlds can be visited
alone, but it is much more fun if you are in the world with other
OZ Virtual, requires Microsoft ActiveX and
Java Virtual Machine. OZ Virtual automatically gets these components
for you. If you run into any problems, or would like to install
the components yourself, you can download ActiveX directly fromhttp://www.oz.com/ov/download/ActiveX.exe,
or find all the components on Microsoft's home page at
You may also choose to download Microsoft
DirectX, which will support 3D sound (DirectSound) in OZ worlds.
This is optional. It can be found at http://www.microsoft.com/directx/resources/downloads/directx.exe.
If you would like to download all the OZ Worlds
to your PC (this will decrease loading time), you can get them
from the directory athttp://www.oz.com/zipvrml.
In general, if you can use Netscape, you should
be able to use OZ. You can't use OZ through Windows-based
on-line services such as America Online, CompuServe, the Microsoft
Network, or Prodigy, unless they support direct Internet access
through the 32-bit Winsock. (Short for Windows Sockets,
Winsock is a standard interface for Microsoft Windows applications
and the Internet. Winsocks allow communication between Windows
Web browsers, e-mail clients, IRC clients, or any other Windows
Winsock applications and the TCP/IP). See, ìSetting up
your on-line service to connect directly with the Internet,î
in Appendix D. If you have further problems, contact your on-line
service for help.
Getting started and a few disclaimers
OZ Virtual is free to use (you have to accept
the terms of your free license during installation). You are not
charged for the time you spend exploring or interacting in OZ
worlds, but you could be charged for the hours you are
online from your Internet service provider (ISP). Check
with your ISP on monthly free hours and rates. Of course, you
should remember that you are also charged by your telephone company
for using the phone line.
More about the companion CD software
OZ Virtual is constantly evolving, and may
have changed since this chapter was written. I placed the very
latest version of OZ Virtual on your book CD, and it may be somewhat
different from what is described here. These differences will
not be major, and this chapter will still be a great guide to
OZ worlds. If you see new features or changes, you should check
for information under the Help menu in OZ Virtual.

UNIX, and OS/2 versions
At this writing, there are no versions of
the OZ Virtual client program for the Macintosh, UNIX, or OS/2.
Check the OZ and Avatars! book Web pages for updates on
new versions which might support these platforms. You also may
be able to run the OZ Virtual client using a Windows emulation
system on non-Windows machines. Note that if you are considering
hosting a complete OZ world, the server software runs on Windows
NT and Windows 95.
Installing OZ Virtual from your Avatars!
If you have a CD-ROM drive on your PC, you
can install OZ Virtual directly from the book CD-ROM. If you don't
have a CD-ROM drive, skip to the following section, ìInstalling
or upgrading OZ Virtual from the Internet.î In Chapter 20,
I provide a step-by-step example of how to install any virtual
worlds software from the CD-ROM. I suggest you refer to this chapter
and follow the same steps for OZ Virtual. Once the installation
program on your CD-ROM has started, you can go to the section,
ìRunning the Installation,î in this chapter.
Installing or upgrading OZ Virtual from
If you want the very latest version of OZ
Virtual, or were informed that you had to upgrade the version
found on your Avatars! CD, then you must download files
from the Internet.
If you don't have any versions of OZ Virtual
on your system, you need to download the initial program from
the Internet. When you start the program, it will prompt you to
download all the components you will need (the rest of OZ Virtual,
ActiveX, DirectSound, Java Virtual Machine). If you haven't done
this before, don't panic, it is easier than you might think!
Running the installation
Whether you are running the installation from
the CD-ROM, or from the file you downloaded from the Internet,
use this section to guide you through the installation. Note that
if you downloaded OZ Virtual from the Internet, the installation
process may have changed. If this has happened, refer to instructions
on OZ Virtual Web site.
1. The installer setup program will run and prompt you at each step. First, read and accept the license agreement terms.
2. Next, you will be prompted for the folder
into which to install OZ Virtual. The default folder is \Program
Files\OZ Interactive\OZ Virtual. You can change this or
accept the default (recommended).

Initiate the download and installation process.
3. Next, you will be prompted to download
and install the components of OZ Virtual from the Internet. This
process (carried out by the OZ Installation Gizmo) will obtain
the needed components and updates for OZ Virtual. As these components
are about 5MB to 10MB in size, this will take some time. I downloaded
OZ Virtual in 30 minutes on a 28.8 kbps modem. The other components
(ActiveX, DirectSound, and Java Virtual Machine) would have taken
another 30 minutes, but since I had Internet Explorer 3.0 installed,
I already had most of these components. The OZ Installation Gizmo
is smart enough to sense what you already have, and will not download

Download a component of OZ Virtual.
4. After all the components are downloaded,
the installation will commence. If you have enough disk space,
and all other necessary components are present the installation
should complete normally.
Files created by the installation
A shortcut to OZ Virtual will be placed on
your desktop. All other files created by the installer should
be found in the folder called \Program Files\OZ Interactive\OZ
Clean up after installation
If you downloaded the OZ Virtual installation
file from the Internet, you can delete it after the installation
is complete. Do not delete the OZ Virtual program in \Program
Files\OZ Interactive\OZ Virtual by mistake as this is your running
