In this short tutorial we will see how to check whether your installed office 2010 product is a 32 bit or 64 bit. One of the way to find these details is by using the options provided as part of the Office 2010 help menu.
Launch any of the office application such as Microsoft Word. Then click the File menu and then navigate to Help menu.
