Q. Your application is not showing in the Application Loader's list of applications.
A. The most common reason for this problem is that Desktop Manager is missing the System Handheld Software that complements it and allows it to properly install 3rd party applications. Sometimes the Desktop Manager itself may also need to be updated to its latest version. See the third question below.

You may also want to try and add the application manually through the "Add..." button in the BlackBerry Desktop Manager. You will need to locate and specify its ALX file, which is a description file containing the list of all files that need to be installed. It is called ALX because of its extensions, which is ".ALX"; its full name will vary depending on the application being installed.

Q. BlackBerry Desktop Manager returns "No additional applications designed for your handheld were found" error when trying to manually add an application (an ALX file).
A. This used to be a problem in older Desktop Manager versions. It was caused by lack of BlackBerry System Handheld Software on the desktop side. BlackBerry Desktop 4.7 and higher automatically download the necessary System Handheld Software so you should not be seeing this error anymore.

Q. When I run Application Loader and go to the "Handheld Application Selection" screen as per your instructions, there are only your applications / there are no applications listed there.
A. Same as above - download and install both the latest Desktop Manager and the System Handheld Software for your phone model.

Q. What is "System Handheld Software" and where do I find it?
A. Desktop Manager 4.7 and later takes care of installing it for you.
