Some programs designed for earlier versions of Windows won't run under Windows XP. Until you can get your hands on a program upgrade for Windows XP, you can try running the program in one of Windows XP Compatibility Modes by following these steps:

1. Double-click the desktop shortcut called Run in Compatibility Mode that's automatically installed there when you install Windows XP to open a full-size Help and Support window with instructions and controls for starting an application in Compatibility Mode.

You can also open this window by clicking Start on the Windows taskbar and then clicking Help and Support on the Start menu. Next, click the Find Compatible Hardware and Software for Windows XP link and then click the Program Compatibility Wizard link at the bottom of the window navigation pane.

2. Read the instructions on the Welcome to Programs Compatibility Wizard screen, paying particular attention to the warning about not using Compatibility Mode on programs, such as anti-virus software and backup tools, that specifically prohibit their use on future editions of the operating system before you click the Next button.

3. In the next screen, click the radio button indicating how you want to locate the program you want to run: I Want to Choose from a List of Programs, I Want to Use the Program in the CD-ROM Drive, or I Want to Locate the Program Manually.

4. If you selected the I Want to Choose from a List of Programs radio button, click the name of the program you want to run in the list that appears before you click Next.
