available online at www.ncomputing.com/documentation
Important installation notes on this release:
 Install on any number of PCs: vSpace Client can be
installed on any number of PCs, laptops or netbooks in your
environment.
 Licensing: Use of vSpace Client is licensed through
vSpace Client Access Licenses (vSCALs) which must be
purchased for and installed on each vSpace Server you
wish to access with vSpace Clients. Each vSCAL entitles
you to make a concurrent connection to a specific server.
Refer to the vSpace Client User Manual for instructions on
loading the vSCAL keys via the vSpace Registration Wizard.
Also, refer to the vSpace Client End User License
Agreement (viewable during installation and available as an
.RTF file in the NComputing vSpace Client installation
directory) for details on your usage rights.

 Microsoft Licensing server required: Microsoft RDS
CALs (for Server 2008 R2) or WMS CALs (for Windows
Multipoint Server) are also required to use the vSpace
Server system in a multi-user configuration. You must also
implement a Microsoft licensing server to enable
connections. For more information on license requirements,
see www.ncomputing.com/mslicensing and refer to the
NComputing Knowledge Base for information on setting up
a license server (search on “licensing” or go to:
http://www.ncomputing.com/kb/How-to-Configure-a-Remote-
DesktopLicensing-Server-for-vSpace-6_281.html).
Tips and Performance Recommendations:
 Performance Profile setting: be sure to use the
Management Console settings in vSpace Server and select
the appropriate vSpace Client performance profile for your
environment (“high-speed network” for LANs and “low-
speed network” for WAN) .
 Clipboard: vSpace Client supports a text clipboard and
allows you to copy text from your local PC desktop and
paste it into your session or vice-versa.
 USB devices: USB devices are only enumerated to your
local PC and not to the vSpace session.
Errata Items:
 Autoconnect to server running in VM – if your vSpace
Client is configured to auto-connect, it may not do so if your
vSpace Server is running in a virtual machine. Check your VM
network settings to ensure that UDP network requests are
accepted.
 Video Streaming: If you overlay other windows on top of a
streaming video, the information (text) in the overlaid window
may become distorted. Whether or not this distortion occurs
depends on the original resolution of the video source and
whether the video is being scaled up on the desktop.
 Full screen Flash – on some hardware platforms, running a
Flash video in full screen mode may result in incomplete video.
Please run in the native or windowed video resolution.
 WAN Logoff: when connected to a vSpace Server session
over a long-distance WAN connection, you may find that the
vSpace Client does not complete the log-off process. If you
encounter this, select the disconnect option from the
vSpace Client overlay menu at the top of the desktop
Audio synch on WiFi networks: when watching a video on a
PC connected to a vSpace Server over a wireless network or
when using a very low-powered client PC, audio and video may

get out-of-synch. If you need closer synchronization, please
use a LAN connection or faster client PC.
