Summary:

This KB article explains the possible reasons for receiving the error “Another version of this product is already installed” when starting a secured instance of SQL Server. It may also appear in the Windows Application Event Log as error 1638.

Additional Information:

There are two possible reasons for this error:

  • You are trying to secure a higher level of SQL Server than your Encryptionizer license allows. For example, your Encryptionizer license permits you to secure Standard Edition, however you are attempting to use it with Enterprise Edition. Please contact us to purchase the appropriate license.

  • You are working with a .SEC profile that was generated using NetLib’s programming API’s and you did not include the KM_PARAMSOK flag (0x01).
