 Thank you for contacting Software Secure Support.

To determine whether your computer is running a 32-bit Windows operating system or a 64-bit Windows operating system, examine the system information. To do this, use one of the following methods.

Note Intel Itanium-based computers can only run 64-bit versions of Windows. Intel Itanium-based computers cannot run a 32-bit Windows operating system. Currently, 64-bit versions of Windows only run on Itanium-based computers and AMD64-based computers.

Windows Vista
Method 1

1. Click Start, type system in the Start Search box, and then click system in the Programs list.
2. The operating system appears as follows:• For a 64-bit version operating system: 64-bit Operating System appears for the System type under System.
• For a 32-bit version operating system: 32-bit Operating System appears for the System type under System.


Method 2

1. Click Start, type system in the Start Search box, and then click System Information in the Programs list.
2. The operating system appears as follows:• For a 64-bit version operating system: x64-based PC appears for the System type under Item.
• For a 32-bit version operating system: x86-based PC appears for the System type under Item.

 

Thank you,
