How to determine whether you have a retail or enterprise edition of Office 2003

This article describes the differences between the two editions of Microsoft Office 2003: Retail and Enterprise. Although the two editions are almost exactly the same, there may be situations where you must determine what edition you own. Use the criteria that this article lists to determine your version of Office 2003.

Office SKU

There are several Office stock-keeping units (SKUs) available for Office 2003. Some of the SKUs overlap between the Enterprise version and the Retail version, 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. NoteMicrosoft Office 2003 Professional Enterprise Edition contains Microsoft Office Infopath 2003.

Use this table to determine what edition you own. If you have Office Professional or Office Standard, use one of the other methods listed later in this article.

.Msi File Name on the CD-ROM

If the Windows Installer .msi package file name on the root of your Office 2003 CD-ROM contains an 'n' in the file name (for example, Pro11n.msi), you are not using an Enterprise edition. The .msi file name extension is not visible unless the folder view setting to display the file extensions is set. If you do not have access to your Office 2003 CD-ROM, use one of the following methods.

Activation Requirement

If you had to activate your Office license, you do not own an Enterprise edition of Office. You obtain Enterprise editions of Office through multiple-license agreements. Therefore, Enterprise editions of Office do not require product activation.

Installation Package (.Msi) File Name

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.

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:

1. Click Start, and then click Run.
2. In the Open box, type:
   regedit
3. Click OK.
4. Locate and select the following registry key:
   HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products
5. 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 2003 Professional is 9040110200063D11C8EF10054038389C.
6. Expand the selected 32-character GUID key.
7. Click the SourceList subkey.
8. Examine the data for the PackageName string value. If the data for this string value contains "n" (for example, Pro11n.msi), you do not have an Enterprise edition of Office. Otherwise, you installed an Enterprise edition.

Installation Source

You can also use the source for your Office installation to determine whether you have an Enterprise edition of Office. If you are installing from a network administrative installation, you have an Enterprise edition of Office. You can only use an Enterprise edition of Office to create a network administrative installation source. 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 edition.
