Note Microsoft Visio Standard 2010, Microsoft Visio Professional 2010, and Microsoft Visio Premium use the product key to determine the product. Therefore, a single product ID is used for all three of these products.

Language identifier

The language identifier (LCID) varies from language to language. Because the LCID is stored in the GUID in hexadecimal format, you may have to convert the LCID value to a decimal value to determine the language of the GUID. For example, a hexadecimal value of 0409 converts to a decimal value of 1033. This value represents English.

Sample GUID

The first 16 digits of a GUID are 91140000-0011-0407. This GUID was created by the initial release version (9) of a Retail or OEM edition (1), version 14.0000, of Microsoft Office Professional 2010 (0014). The language of the product is German. In this case, the hexadecimal value 0407 converts to the decimal value 1031. This value represents German.
