Introduction

This article describes how to determine whether you have a retail edition or volume license edition of the Microsoft Office 2010 or 2007 suite.

Methods

To determine whether you have a retail edition or a volume license edition, use one of the following methods.

Method 1: Examine the contents of the installation disc

  1. Insert the 2010 or 2007 Office suite installation disc into the computer's CD or DVD drive.

    Note

    If you have multiple discs, use disc 1. In the case of a DVD, the disc must be inserted into a DVD drive.

  2. When the Setup window is displayed, close the window.

  3. Select Start > My Computer.

  4. Right-click the CD or DVD drive that contains the disc, and then select Explore.

  5. Look for a folder that is named Admin.

    • If the Admin folder exists, this disc is a volume license (VL) edition.
    • If the Admin folder does not exist, this disc is a retail edition.

    Note

    Retail media includes a lowercase "r" before the ".WW" in the folder name and before the "WW.msi" in the msi file name. For example, Enterprise retail would be EnterpriserWW.msi in the Enterpriser.WW folder. Enterprise non-retail would be EnterpriseWW.msi in the Enterprise.WW.

Method 2: Examine the registry on the computer

Warning

Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

  1. On a computer that has Office 2010 or 2007 installed, select Start, select Run, type regedit, and then select OK.

    Note

    If you are running Windows 7, we recommend that you run Registry Editor in Administrator mode. To do that in Windows 7, follow these steps:

    1. Select Start and type cmd.
    2. Right-click Command Prompt in the results list, and then select Run as Administrator.
    3. Type Regedit, and press Enter.
  2. Locate and then select the following registry subkey: HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products

  3. In the navigation area on the left side, expand the Products entry node, and then select each 32-character {GUID} until you locate the one whose ProductName value in the topic area matches your version of the 2010 or 2007 Office suite. For example, the 32-character {GUID} for Microsoft Office Professional Plus 2010 appears as follows:

    {BRMMmmmm-PPPP-LLLL-p000-D000000FF1CE}

    The 32-character {GUID} for Microsoft Office Professional Plus 2007 appears as follows:

    00002103110000000000000000F01FEC

  4. Expand the selected 32-character GUID entry.

  5. Select the SourceList entry.

  6. In the topic area, examine the data for the PackageName string value.

    • If the data here contains the letter "r" before "WW," this is a retail edition of Office. For example, you may see ProrWW.msi or StandardrWW.msi.
    • If the string value does not contain the letter "r" before "WW," this is a volume license edition of Office. For example, you may see ProWW.msi or StandardWW.msi, depending on which version of Office (Professional or Standard) you have installed.
  7. Exit Registry Editor.
