SUMMARY
This article describes how to determine which version of Exchange 2000 is installed on your server, and explains the differences between the versions.



Determining the Version
 Start Registry Editor (Regedt32.exe). Locate the following key in the registry:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

 Find the appropriate GUID registry subkey as listed below. Verify that the DisplayName in the right pane equals Microsoft Exchange 2000. The following subkeys indicate the version of Exchange 2000 that is installed on the server:  DB20F7FD-67BC-4813-8808-78F63E89EB56: Standard Version Upgrade Package (VUP) 775CF3DA-C007-4709-B4CC-CE2239BE2E03: Standard Full Packaged Product (FPP) FC6FA539-452D-4a9b-8065-C1FA74B86F83: Standard Evaluation 120 days (EVAL) D3574E0C-360A-44d5-858C-33323C2D79F2: Enterprise Version Upgrade Package (VUP)</li> F8567801-906B-439b-8D6A-87BDFEC9BA52: Enterprise Product Upgrade Package (PUP)</li> 65D9643D-06E8-47d6-865E-80F4CC9BB879: Enterprise Full Packaged Product (FPP)</li> 8B102332-6052-4af3-ADFA-35A3DED0506A: Enterprise Evaluation 120 days (EVAL)</li></ul>

NOTE: Microsoft does not support attempts to change the value of this registry key. If you change the subkey value, it will not change the version or functionality of the Exchange 2000 software that is installed.

</li> Quit Registry Editor.</li></ol>

Product Version Summary

 * Full Packaged Product (FPP): This is a complete product that has no limitations.
 * Version Upgrade Package (VUP): This is the upgrade only to upgrade from a previous version of the product to the current version (for example, upgrading from Microsoft Exchange Server 5.5 Standard Edition to Exchange 2000 Standard Edition).
 * Product Upgrade Package (PUP): This is only for a product of the same release (for example, an upgrade from Exchange 2000 Standard Edition to Exchange 2000 Enterprise Edition).
 * Evaluation Edition (EVAL): This is identical to the FPP version except that it expires 120 days from the date of installation.

IMPORTANT: If you manually remove Exchange 2000, this registry key will still exist. It is represented by &quot;Microsoft Exchange 2000&quot; in the Add/Remove Programs tool. If you delete the registry key, &quot;Microsoft Exchange 2000&quot; is removed from Add/Remove Programs.
