SYMPTOMS
When you install a 32-bit application on a computer that is running a 64-bit version of Microsoft Windows Server 2003, you may find that the 32-bit application is not initialized and installed correctly for a new user who logs on to the computer.



CAUSE
This problem occurs because of the way that the active setup registry subkeys define installed components. Every time that a user logs on, the operating system examines these subkeys to make sure that the user initiates all the applications. The operating system examines these subkeys by running a user-independent setup string.

By default, The application settings are defined in the following registry subkey:

When a 32-bit application installs, it adds itself to the registry in the following registry subkey:

When a user logs on to a computer that is running a 64-bit version of Windows Server 2003, only the 64-bit registry subkeys are examined. The Wow6432Node registry entry is ignored. Therefore, 32-bit applications are not installed correctly.
