SUMMARY
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 SKU
There 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.
Office SKU Editions available
-----------------------------------------------------
Professional with FrontPage Enterprise
Professional Enterprise and Retail
Standard Enterprise and Retail
Small Business Retail (OEM)
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-ROM
Another 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-ROM
If 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 Requirement
If 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 Name
If 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.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
- Click Start and then click Run.
- In the Open box, type regedit and then click OK.
- Locate and select the following registry key, according to the version of Microsoft Windows that you use.
Windows Version Registry Location
------------------------------------------------------------------------
Windows NT 4.0 or
Windows 2000 HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products
Windows 98 or
Windows Me HKEY_CURRENT_USER\Software\Microsoft\Installer\Products
- Below the \Products key, select each 32-character {GUID} until you find the one whose ProductName value matches your version of Office. For example, the 32-character {GUID} for Office XP Professional with FrontPage is 9040820900063D11C8EF00054038389C.
- Expand the selected 32-character GUID key.
- Select the SourceList subkey.
- Examine the data for the PackageName string value.
If the data for this string value contains "ret" or "tri" (for example, Proret.msi or Protri.msi), you installed a Retail edition. If it does not contain "ret" or "tri" (for example, Pro.msi or Proplus.msi), you installed an Enterprise edition.

Installation Source
Finally, you can also tell whether you have an Enterprise or Retail edition of Office by the source for your Office installation. If you are installing from either of the following two sources, you have an Enterprise edition of Office:
- Network administrative installation
- Web URL (through a browser)
These two Office installation sources can only be created with an Enterprise edition of Office.
If you are using a CD-ROM to install Office, use one of the methods listed earlier in this article to determine whether you have an Enterprise or Retail edition.
