"Class does not support Automation or does not support expected
interface"
This error may occur when software attempts to access a database file by referencing
libraries that are a different version than those installed on the computer. Microsoft
provides a set of software libraries that programs use to interact with databases; these
libraries are known collectively as Microsoft Data Access Components (MDAC). These
components are normally included with application programs that need them and are
installed automatically during the setup process. A problem can occur if the incorrect
version of MDAC is included on the installation disk, or if MDAC is already installed on
the computer and the setup process does not overwrite MDAC with the new version. When the
software references one version of MDAC but a different (usually older) version is
installed, Error 430 is the result.
The best solution is to download and install the latest MDAC version from Microsoft's web
site (as 12/05/02, the latest version is 2.6, SP2)
