 class doesn't support automation or doesn't support expected interface

Hello, please help me it's very urgent:

Developed application in VB6 - win2k - office2000, and i've made setup
package.

I want to install it onto a machine what have office97 (not office2000) and
i get the error (i open access database)

"class doesn't support automation or doesn't support expected interface"

If i install office2000, it works properly. What's the reason????

The reason is that you are not deploying all the files your application
requires; my guess is you are omitting MDAC_TYP.EXE, which contains the
necessary ADO libraries. One of these is missing or of an incorrect version.

Check your package and ensure you are including the version of mdac_typ.exe
that contains the provider you are using. Bear in mind that Jet-based
drivers and providers (dBase, Paradox, Access, etc) are no longer present
in MDAC 2.6 and later.  If you are using Access, you should install 2.5 sp2
and be sure you are using the Jet OLEDB Provider version 4.0.

You can download MDAC from http://www.microsoft.com/data.

Hope this helps!
