36 MetaFrame Solutions Guide

short, a separate install must be done for each user who wants to use the

application.

If an application is installed with the user-specific method, no special

considerations regarding the storage and retrieval of data are needed. However,

because the application must be completely installed once for each user, this

method can consume a large amount of disk space and adds to administrative

overhead in larger environments.

Some applications offer the option of doing a network installation. This process

copies the installation diskettes or CD-ROM files to a common directory on the

network from which individual users can then run a SETUP or INSTALL utility,

which copies the required Ini files to their home Windows directory. While it does

use less space on the MetaFrame server than multiple user-specific installations, it

still requires that a separate process be run for each user.

User-Global

Citrix recommends using the user-global method of installing Windows

applications. With this method, an application is installed once by an administrator

and can be run by anyone who logs on to that MetaFrame server.

To perform a user-global install, use either of the following methods:

Use the Add/Remove Programs utility in Control Panel to initiate the

installation

Use the change user /install command at the command prompt before

installing the application and change user /execute after installing the

application

The Add/Remove Programs utility and the change user /install command place

the session into install mode. This ensures that Ini files are installed to the

Windows 2000 system directory instead of the user’s home Windows directory.

When the installation is complete, the Add/Remove Programs utility and change

user /execute command place the session back into execute mode. When a user

starts the application for the first time, the required user-specific files are

automatically copied to the user’s home directory.

Most Win32 applications install in a pseudo user-global fashion by default, even

when the session is not in install mode, because they make use of the Windows

2000 registry, where each user can have a unique set of registry settings. Win16

applications use Ini files for configuration settings so they must be installed using

install mode in order for multiple users to get separate copies of these files. It is

recommended that you always install any Windows application, whether 16- or

32-bit, using install mode. For security reasons, it is also recommended that you

install applications on Windows NT file system (NTFS)-formatted drives rather

than on FAT-formatted drives.
