standard AT&T Global Network Client Installer package should also apply to AT&T Global Network Client
packages that have been customized with a transform if the transform has been implemented correctly.
To preserve as much as possible of the typical behavior of the standard Windows Installer package, your
transform should make as few changes as possible. That means that you should first try to accomplish
the modification by changing values in the Property table, rather than by making more extensive changes
in the MSI database. It is recommended all changes are done with a minimalist approach to avoid
unintended consequences.
Tools to Create a Transform
Microsoft Windows Platform SDK contains tools which can assist you in creating a transform. You must
obtain and install the Windows Platform SDK relevant to your operating system to have access to the
tools.
The Microsoft tool named Orca can open and edit MSI transform files. When Orca is installed as part of
the Windows Platform SDK, you can right click on MSI files and select the option Edit with Orca.
When viewing an AT&T Global Network Client MSI file with Orca the public properties will be shown in
the Orca Property Table. Properties not listed in the Orca Property Table, but listed in this document can
be added to the Orca Property Table for editing. Select Add Row in the Orca Property Table to add fields
and corresponding values.
