You may also receive the following error message when you try to run a backup of a SQL Server database:

Could not create component: x80040154

Check registration of SQLVDI.DLL and value of IID



CAUSE
This problem occurs when the backup program tries to use a Sqlvdi.dll file that has been unregistered. Typically, the Sqlvdi.dll file can become unregistered when you uninstall SQL Server Desktop Engine (also known as MSDE 2000) from a computer that is also running Microsoft SQL Server 2000.



RESOLUTION
To resolve this problem, re-register the Sqlvdi.dll file. To do so, follow these steps:
 * 1) Stop SQL Server.
 * 2) Click Start, click Run, type Regsvr32  \SQLVDI.DLL in the Open box, and then click OK. The default path of the Sqlvdi.dll file is C:\Program Files\Microsoft SQL Server\80\COM.
 * 3) Restart SQL Server.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section of this article.
