SYMPTOMS
Repositories created in SQL Server 2000 by Visual Component Manager (VCM) on a computer that has the SQL Server 2000 server or client components installed cannot be accessed from a Visual Component Manager client on a computer without these components. The following error message will appear:

Error: Installing Model File Error: Creating Repository Failed Incompatible repository database version.



CAUSE
SQL Server 2000 installs Repository 3.0. Clients with Visual Basic or Visual Studio 6.0 have Repository 2.0, which uses a different repository schema.



RESOLUTION
Install at least the SQL Server 2000 client components on the Visual Component Manager client computer. Or, install only the SQL Server 2000 Repository redistributable components using the instructions found in Redist.txt on the SQL Server 2000 installation CD.



STATUS
This behavior is by design.



MORE INFORMATION
SQL Server 2000 installs Repository 3.0 and, if you use the installation of Visual Component Manager on a computer that has the SQL Server 2000 server or client components installed to create the repository, it uses Repository 3.0.

If you create a VCM repository using Repository 3.0, you must upgrade all VCM clients accessing that repository to Repository 3.0.

Repositories created with Repository 2.0/2.1 are accessible from a VCM client with Repository 3.0; in other words, Repository 3.0 is backward-compatible.

Installing SQL Server 2000 server or client components installs MDAC 2.6, and clients accessing SQL Server 2000 should normally install MDAC 2.6. However, the problem discussed in this article is not related to MDAC version.
