Creating a Custom Compatibility Mode in Compatibility Administrator
Updated: May 31, 2012
Applies To: Windows 7, Windows 8, Windows 8.1, Windows Vista
Windows® provides several compatibility modes, groups of compatibility fixes found to resolve many common application-compatibility issues. While working with Compatibility Administrator, you might decide to group some of your individual compatibility fixes into a custom-compatibility mode, which you can then deploy and use on any of your compatibility databases.
A compatibility mode is a group of compatibility fixes. A compatibility fix, previously known as a shim, is a small piece of code that intercepts API calls from applications. The fix transforms the API calls so that the current version of the operating system supports the application in the same way as previous versions of the operating system. This can be anything from disabling a new feature in Windows to emulating a particular behavior of an older version of the Windows API.
The Compatibility Administrator tool has preloaded fixes for many common applications, including known compatibility fixes, compatibility modes, and AppHelp messages. Before you create a new compatibility mode, you can search for an existing application and then copy and paste the known fixes into your custom database.
|Application Compatibility Toolkit (ACT) installs a 32-bit and a 64-bit version of the Compatibility Administrator tool. You must use the 32-bit version to create custom databases for 32-bit applications and the 64-bit version to create custom databases for 64-bit applications.|
In the left-side pane of Compatibility Administrator, expand the Applications folder and search for your application name.
Click the application name to view the preloaded compatibility modes, compatibility fixes, or AppHelp messages.
If you are unable to find a preloaded compatibility mode for your application, you can create a new one for use by your custom database.
|A compatibility mode includes a set of compatibility fixes and must be deployed as a group. Therefore, you should include only fixes that you intend to deploy together to the database.|
In the left-side pane of Compatibility Administrator, underneath the Custom Databases heading, right-click the name of the database to which you will apply the compatibility mode, click Create New, and then click Compatibility Mode.
Type the name of your custom-compatibility mode into the Name of the compatibility mode text box.
Select each of the available compatibility fixes to include in your custom-compatibility mode and then click >.
Important If you are unsure which compatibility fixes to add, you can click Copy Mode. The Select Compatibility Mode dialog box appears and enables you to select from the preloaded compatibility modes. After you select a compatibility mode and click OK, any compatibility fixes that are included in the preloaded compatibility mode will be automatically added to your custom-compatibility mode.
If you have any compatibility fixes that require additional parameters, you can select the fix, and then click Parameters. The Options for <Compatibility_Fix_Name> dialog box appears, enabling you to update the parameter fields.
After you are done selecting the compatibility fixes to include, click OK.
The compatibility mode is added to your custom database.
