The Compatibility Administrator tool enables you to create an AppHelp text message. This is a blocking or non-blocking message that appears when a user starts an application that you know has major functionality issues on the Windows® operating system.
Blocking Versus Non-Blocking AppHelp Messages
A blocking AppHelp message prevents the application from starting and displays a message to the user. You can define a specific URL where the user can download an updated driver or other fix to resolve the issue. When using a blocking AppHelp message, you must also define the file-matching information to identify the version of the application and enable the corrected version to continue.
A non-blocking AppHelp message does not prevent the application from starting, but provides a message to the user including information such as security issues, updates to the application, or changes to the location of network resources.
Searching for Existing Compatibility Fixes
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 AppHelp message, 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.|
To search for an existing application
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 AppHelp messages, compatibility fixes, and compatibility modes.
Creating a New AppHelp Message
If you are unable to find a preloaded AppHelp message for your application, you can create a new one for use by your custom database.
To create a new AppHelp message
In the left-side pane of Compatibility Administrator, below the Custom Databases heading, right-click the name of the database to which you will apply the AppHelp message, click Create New, and then click AppHelp Message.
Type the name of the application to which this AppHelp message applies, type the name of the application vendor, browse to the location of the application file (.exe) on your computer, and then click Next.
The wizard shows the known Matching Information, which is used for program identification.
Select any additional criteria to use to match your applications to the AppHelp message, and then click Next.
By default, Compatibility Administrator selects the basic matching criteria for your application.
The wizard shows the Enter Message Type options.
Click one of the following options:

to run. This is a non-blocking message, which means that you
can alert the user that there might be a problem, but the
application is not prevented from starting.
- Display a message and do not allow this
program to run. This is a blocking message, which means that
the application will not start. Instead, this message points the
user to a location that provides more information about fixing the
