If you try to import, export, or link (attach) a file by using an indexed sequential access method (ISAM) driver, you may receive an error message if Microsoft Access cannot find the ISAM driver.

ISAM drivers are used by Microsoft Access to update file formats other than its own.

In Microsoft Access 2.0, if the path to the ISAM driver in your Msacc20.ini file is invalid, or if the ISAM driver does not exist, you may receive the following error message:

Microsoft Access 7.0 and 97 do not have an .ini file. Information previously stored in the .ini files is now stored in the Microsoft Windows Registry. In Microsoft Access 7.0 and 97, if the path to the ISAM driver in your Windows Registry is invalid, or if the ISAM driver does not exist, you may receive the following error message:

This error can also occur if you enter an invalid database name for a SQL database when you are using the TransferDatabase action in a macro. When you use an invalid connect string, Microsoft Access looks for an installable ISAM for the SQL database. If an installable ISAM cannot be located, an error occurs.
