How to determine whether you have a retail edition or a volume license edition of a 2007 Microsoft Office suite

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

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 2007 Office suite installation disc into the computer's CD drive or DVD drive.
   
   Note If you have multiple discs, use disc 1. Also, check the disc label for the DVD symbol. If you see this symbol, the disc must be inserted into a DVD drive.
2. When the Setup window is displayed, close the Setup window.
3. Click Start, and then click My Computer.
4. Right-click the CD drive or the DVD drive that contains the disc, and then click Explore.
5. Look for a folder that is named Admin.
   • If the Admin folder exists, this disc is a volume license 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. Notice the absence of the lowercase "r" in the non-retail names.

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 a 2007 Office suite installed, click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products
3. Expand the Products entry node in the navigation area, and then click each 32-character {GUID} until you locate the one whose ProductName value in the topic area matches your version of the 2007 Office suite. For example, the 32-character {GUID} for Microsoft Office Professional Plus 2007 appears as follows:
   00002103110000000000000000F01FEC

4. Expand the selected 32-character GUID entry.
5. Click the SourceList entry.
6. In the topic area, examine the data for the PackageName string value.
   • If the data for this string value contains the letter "r" before "WW," this is a retail edition of a 2007 Office suite. For example, the data may be displayed as "ProrWW.msi" or as "StandardrWW.msi."
   • If the data for this string value does not contain the letter "r" before "WW," this is a volume license edition of a 2007 Office suite. For example, the data may be displayed as "ProWW.msi" or as "StandardWW.msi."
7. Exit Registry Editor.
