The 64-bit (x64) operating systems are specifically designed to handle programs and hardware that use the 64-bit architecture. However, using a 64-bit operating system does not in any way stop you from installing or running programs that use the older 32-bit (x86) architecture. Installing a 32-bit program on to a 64-bit operating system is in no way different to the procedure that it takes to install a 64-bit program.
Insert the installation CD or DVD of the 32-bit program and click the “Install” link on the Autorun menu.
Agree to the license agreement of the program, and specify a location to install it. By default, the program will get installed to the “Programs File (x86)” folder on the hard disk partition of the Windows installation.
Follow any other instructions on the installation setup to install the 32-bit program. After installing, you can access the 32-bit program from the Windows Start menu.
