Many processor vendors (ie. AMD, Intel) are introducing a feature
referred to as NX (no-execute) that prevents data memory areas from
executing code.  With the installation of Microsoft Windows XP SP2
(Service Pack 2), Data Execution Prevention (DEP) enables the NX
feature.  With this NX feature enabled, certain client applications
could crash or fail to execute.

The following message may be displayed when executing the client (in
this example, the client is the Integration Technologies Configuration
Utility - ITCONFIG) :

   Data Execution Prevention - Microsoft Windows
   To help protect your computer, Windows has closed this program.

   Name:  itconfig Module
   Publisher:  SAS Institute Inc.

Pressing "Continue" generates:

    itconfig Module has encountered a problem and needs to
    close.  We are sorry for the inconvenience.

In the Data Execution Prevention Window that is automatically displayed
when the NX feature is enabled, the "Change Settings" button allows you
to bypass the DEP option for all programs and services except for the
applications that are selected.  By checking the client application,
and selecting "OK", the first time that the application is executed the
above error will be displayed but the application will work each time
there after.

To correct the problem and allow the client application to work with the
DEP option, download and install the Integration Technologies Client for
Windows (Release 9.1) INTTECH.EXE module, found at the following
location:
