Have you followed these guide lines:
Installing Workstation Setup
From a Terminal Services/Citrix desktop, run Workstation Setup logged on as
an administrator. Do not run Workstation Setup directly at the Terminal
Server.
1 Insert the Workstation Setup CD-ROM into the Terminal Services Server
CD-ROM drive. Close the Autorun screen that appears when the CD-ROM
is inserted.
2 From the Terminal Services Server session, open the Start menu, click
Settings and then Control Panel. Click Add/Remove Programs.
To correctly install in Terminal Server, you must install using the
Add/Remove Programs routine. In the Add/Remove Programs window,
click the Add New Programs icon on the left side of the window and then
click CD-ROM or Floppy
After clicking CD-ROM or Floppy, a wizard appears that walks you
through the rest of the installation. The wizard automatically searches
your CD-ROM and floppy disk drives for a setup.exe program. To install
from across the network, type a path if a CD-ROM or floppy disk is not
available.
Because multiple users will use the MAS 200 client, a multi-user activation
key is required. To obtain this key, you must first activate the server
before running Workstation Setup. This causes a multi-user activation key
to be copied to the MAS 200 client directory on the Terminal Services
Server.
Whether using the MAS 200 or the MAS 200 Workstation CD-ROM, make
sure to specify the correct path to the workstation setup.exe file, for
example, D:\Wksetup\Setup.exe where D:\ is the CD-ROM drive letter.
The wizard runs the setup.exe routine you specified in the previous
window
Terminal Services Considerations
MAS 200 will retrieve the workstation name of the client that is coming into
the Terminal Server environment and will use that workstation's name for
tracking sessions. This allows for a single installation of Workstation Setup
that all users can access; however, verify that all user's machines that are
coming in through the Terminal Server have unique workstation names.
Because multiple users will use the MAS 200 client, a multi-user activation
key is required. To obtain this key, you must first activate the server. After the
server is activated, running Workstation Setup through a Terminal Server
desktop session (not directly at the server) will copy the ACTIVATE.PVX file
in the MAS 200 Server's MAS90\Home\Lib\Keys directory to the
MAS90\Home\Lib\Keys directory of the MAS 200 client on the Terminal
Server.
MAS 200 can be used under the Terminal Server with the permissions
compatibility set to either Windows 2000 or Windows NT 4.0; however,
Windows 2000 security requires that the group, Users, be explicitly granted
Full Control to the MAS 200 directory of the client if it is installed on an NT
File System (NTFS).
To grant Full Control to the client installed on an NTFS
1 In Windows Explorer, locate the MAS 200 directory (by default, this is in
the C:\Program Files\Best directory).
2 Right-click the MAS 200 directory.
3 Click Properties.
4 Select the Users group.
5 Select Full Control (doing this selects all permissions automatically).
6 Click OK.
