Deployment Problem (ADO)

Posted on 2001-06-06

Last Modified: 2010-05-02
I am trying to deploy a VB6 app that includes Esri Map Objects components and ADO ODBC database access to Oracle and MS Access databases.

After installation, when the app is run we get the error message "Provider not found".  Because of past knowledge we know that this is a problem concerning ADO.  To get around the problem we can install VB onto the client PC but we know that this is not the ideal answer.

Any ideas?

Have you included MDAC_TYP.EXE in the installation package. If not then you should do, however you can easily install this seperately. Download the appropriate version of it from http://www.microsoft.com/data and install it on the target machine.

You need to deploy mdac_type.exe on their machines which installs ADO only.

This may be downloaded from

Ideally you should include Microsoft Data Access Components(MDAC_TYP.EXE) as part of the Package and deployment wizard - of course this can be done by installing it onto the server and running it on the client machines later - at least this way you know then that everyone is using the same version of MDAC which is currently 2.6.
Just a quick point - always ensure that all controls etc that are used in your application are included in your setup package.

Good Luck

If you're not using the MS provided Oracle provider, you'll need to send along the one you are using.

Trust me, Microsoft have made the interdependency between all the dlls comprised in mdac_type *such* a nightmare that anything other than including mdac_type as suggested by several people already, is sheer madness.

If the missing provider turns out to be the Jet Engine, it might be due to the fact that you installed ADO version 2.6 on the client(s), which does not include Jet drivers anymore.

See the KB Article ID Q271908, "MDAC Version 2.6 Does Not Contain Jet" at http://support.microsoft.com/support/kb/articles/Q271/9/08.asp

If your problem is when you connect to the Access database, be sure you use the 4.0 provider (and not the 3.51 provider). This version is written into your connection string.
