MORE INFORMATION

The kinds of problems that are resolved by application compatibility updates

When you try to install and to run certain legacy games or applications in Windows Vista, you may experience one or more of the following symptoms:
  • The game, the application, or the firmware may not be installed correctly.
  • The game, the application, or the firmware may cause system instability.
  • The primary functions of the game, the application, or the firmware may not work correctly.

Applications that will experience a change in behavior after you install this update

The following table shows the applications that were added to the December 2007 cumulative update package, and the behavior of the application after you install the update.

Application compatibility updates cause several behaviors in Windows Vista. The following are the three most common behaviors:
  • Hard Block: The update puts a hard block on the application. A hard block prevents an application that is incompatible with Windows Vista from running on the operating system.

    Note Microsoft puts a hard blocks on a non-Microsoft application only when the manufacturer of the application gives their consent.
  • Soft Block: The update puts a soft block on the application. A soft block provides notification when an application that is incompatible with Windows Vista starts to run.
  • Update: The update improves the application’s functionality in Windows Vista.

How to troubleshoot application compatibility issues that are not resolved by the latest application compatibility update

Perform the following troubleshooting steps if you install the latest version of the application compatibility update and still experience application compatibility issues in Windows Vista:
  • Restart the computer after you install the application compatibility update to enable any additional process to complete and drivers to be loaded correctly.
  • Run the program in compatibility mode.
    When you run the program in compatibility mode, Windows Vista emulates the selected operating system when you run that particular program.

    To run the program in compatibility mode, follow these steps:
    1. Click Start

      Start button
      , and then type the name of the program in the Start Search box.
    2. In the Programs list, right-click the program name, and then click Properties.
    3. On the Compatibility tab, click to select the Run this program in compatibility mode for check box.
    4. In the list, select an operating system, and then click OK.
  • Contact the program vendor
    If a program will not run in Windows Vista, or if a piece of hardware does not function as expected after you install Windows Vista, contact the program vendor or the hardware manufacturer for guidance about how to troubleshoot the issue. Typically, the software vendor's Web site provides a support section that includes more information about compatibility.

    Frequently, the software vendor will be able to resolve the incompatibility issue by providing one of the following resolutions:
    • An update to make the current version of the program compatible with Windows Vista.
    • A version of the program that is compatible with Windows Vista.
    • Information about any configuration changes that will make the program compatible with Windows Vista.
