Windows XP Compatibility Mode
When installing or starting an older program under Windows XP, if
the program fails to run or causes problems with Windows XP, try
using "compatibility mode". Compatibility mode allows you to adjust
various environmental settings that could cause the program to fail.
Keep in mind that Windows XP is based more on Windows NT and not
Windows 95 or 98.
To adjust the compatibility mode of a program that has already been
installed to your hard drive, locate the executable program in your
hard drive folders. Right click on the program (or shortcut link)
and select "Properties". Click on the "Compatibility" tab. Click
on "Run this program in compatibility mode" and select the environment
that the program was designed for. Your choices for compatibility
- Windows 95
- Windows 98
- Windows NT 4
- Windows 2000
Other compatibility settings include being able to limit the number
of colors to 256, run in 640x480 resolution, and to disable themes.
When you are done with the selections, click on Apply, then OK to
save the changes. Double click on the program to start. If the Windows
XP environment is the problem, then it should run with the settings
you have specified.
You can use compatibility mode on programs located on CD-ROM or
Floppy disk, but the changes are not retained after you exit the
If the program still fails to run or causes problems with Windows
XP, you may need to INSTALL the program in compatibility mode. The
process is identical to what is described above, but instead of
right clicking on the program itself, right click on the Setup or
Install program to set compatibility mode options.
One example of a program that this could make a difference with
is scanner software and its twain driver. When the program is installed
"normally", setup proceeds as if the system was Windows 95 or 98.
The scanner setup makes changes and additions to your CONFIG.SYS
and AUTOEXEC.BAT files, and loads several device drivers to the
hard drive. Windows XP does not load anything from these files during
startup. Since the twain software is installed, but the required
device driver is "missing", Windows XP reboots as soon as you try
to run the twain software to scan. (This is not a good thing. A
program crash that causes Windows XP to reboot could cause hard
drive corruption and data loss.)
The solution here is to un-install or remove the old software,
and then run the Install again using compatibility mode. By selecting
"Windows NT 4" as the environment, the scanner software does not
modify the CONFIG.SYS and AUTOEXEC.BAT files, and loads a different
set of device drivers. After installing the software this way, the
scanner software ran fine, providing twain driver support in Windows
XP and various graphics applications.
This does not mean that compatibility mode will solve all your
problems, but it is a Windows XP feature that provides you with
some backward-compatibility and may allow you to keep using that
old software or hardware a little longer. Watch for warnings from
the software that may indicate a serious incompatibility with an
Operating System other that the one it was designed for. Programs
such as Disk Utilities, Backup software and some CD-R burning software
could cause serious problems by trying to directly access hardware
instead of working through the Windows environment.
You can also run the "Compatibility Wizard" to guide you through
this process. To start the wizard click "Start", "Programs", "Accessories",
then "Program Compatibility Wizard". A second method to access the
wizard is by using the Windows Help and Support screens. Click "Start",
"Help and Support", then click on "Problems with your Applications
after upgrading? Try the Program Compatibility Wizard." under the
"Did you know?" section.
