If you create an installer for your application, the installer can update registry settings so that your application appears in the BlackBerry Application Loader in Desktop Manager. Although it is optional, users do not have to manually click Add in the Application Loader to select the ALX file. Add a string (REG_SZ) value to the following registry key:
HKEY_CURRENT_USER\Software\Research In Motion\BlackBerry\Loader\Packages
Create the registry value as follows:
The value name is the same as in the ALX file. By default, this is the same as the project name in the integrated development environment IDE (for example, com.rim.helloworld).
The value data is the full path to the location where you install the ALX file on the user's personal computer (for example, C:\temp\Files\samples\sampleapp.alx).
