This step-by-step article explains the differences between the two editions of Microsoft Office XP: Retail and Enterprise. Although the two editions are nearly identical, there may be situations in which you need to determine which edition you own or have installed. Use one or more of the criteria listed in this article to establish your version of Office XP.
Office SKUThere are multiple Office stock-keeping units (SKUs) available for Office XP. Some of the SKUs overlap between Enterprise and Retail, but some SKUs are only available in one edition or the other. The following table lists the different Office SKUs that are available for Enterprise and Retail editions.
Use this table to determine which edition you own. If you have either Office Professional or Office Standard, use one of the other methods listed later in this article.

Contents of the Office XP CD-ROMAnother way to determine whether you own an Enterprise edition of Office is to view the contents of the Office CD-ROM. If your CD-ROM has a folder called "ORK," you have an Enterprise edition of Office.
.Msi File Name on the CD-ROMIf the Windows Installer .msi package file name on the root of your Office XP CD-ROM contains "ret" or "tri" (for example, Proret.msi or Protri.msi), you have a Retail edition. If it does not contain "ret" or "tri" (for example, Pro.msi), you have an Enterprise edition.
If you do not have access to your Office XP CD-ROM, use one of the following methods.
Activation RequirementIf you were required to activate your Office license, you own a Retail edition of Office. Enterprise editions of Office are obtained through multiple-license agreements and do not require product activation.
Installation Package (.Msi) File NameIf Office is installed on your computer, you can check the Windows registry for the name of the Windows Installer package that was used during the Office installation. To do this, follow these steps.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.
