This article describes the numbering scheme used by Microsoft Office programs and utilities.
When you install Office, or any of the stand-alone Office programs, a product code or GUID is created in the following section of the Microsoft Windows registry:
The format used by each GUID is:
The first section of the GUID contains information about the version, store-keeping unit (SKU), and language of the product:
AllowableCharacters Definition values-------------------------------------------------------------xx The version of the product 00-FFyy The SKU of the product 00-FFzzzz The language identifier of the product any required
This scheme allows for up to 255 versions for each of 255 SKUs for each language version of Office. All three of these values are stored in hexadecimal format within the GUID.
The version number starts at 00 for the initial released version of Office and each stand-alone Office program. When new versions or service releases are released, the version number will be incremented (01, 02, 03).
The SKU number is different for each package of Office or stand-alone Office program, as shown in the following table.
SKU number Program ----------------------- 00 Microsoft Office 2000 Premium Edition CD1 01 Microsoft Office 2000 Professional Edition 02 Microsoft Office 2000 Standard Edition 03 Microsoft Office 2000 Small Business Edition 04 Microsoft Office 2000 Premium CD2 05 Office CD2 SMALL 06-0F (reserved) 10 Microsoft Access 2000 (standalone) 11 Microsoft Excel 2000 (standalone) 12 Microsoft FrontPage 2000 (standalone) 13 Microsoft PowerPoint 2000 (standalone) 14 Microsoft Publisher 2000 (standalone) 15 Office Server Extensions 16 Microsoft Outlook 2000 (standalone) 17 Microsoft Word 2000 (standalone) 18 Microsoft Access 2000 runtime version 19 FrontPage Server Extensions 1A Publisher Standalone OEM 1B DMMWeb 1C FP WECCOM 1D-1F (reserved standalone SKUs) 20-2F Office Language Packs 30-3F Proofing Tools Kit(s) 40 Publisher Trial CD 41 Publisher Trial Web 42 SBB 43 SBT 44 SBT CD2 45 SBTART 46 Web Components 47 VP Office CD2 with LVP 48 VP PUB with LVP 49 VP PUB with LVP OEM 4F Access 2000 SR-1 Run-Time Minimum
The language identifier, or LCID, varies from language to language. Since the LCID is stored in the GUID in hexadecimal format, you may need to convert it to decimal in order to determine the language of the GUID. For example, 0409 hexadecimal is equivalent to 1033 decimal, which translates to English.Note
The remaining digits (78E1-11D2-...) do not provide any easily categorizable information.
So, if the GUID begins with 00020407, you would know that the GUID was created by the initial released version (00) of Microsoft Office 2000 Standard Edition (02) and that the language of the product is German (0407 hexadecimal = 1031 decimal = German).
You can view the GUIDs for programs that are installed on your computer by following these steps:
- Click Start, click Run, type regedit in the Open box, and then click OK.
- Locate the following subkey:
The GUIDs should be the first items listed under Uninstall
because their names start with braces.
Each GUID's data pane contains multiple values, including the product name that appears in the Add/Remove Programs
dialog box (DisplayName), the date that the product was installed (InstallDate), the product ID (Product ID), the installation source (InstallSource), and the registered company and user name (RegCompany, RegOwner).
