This article was previously published under Q268264
When you import data from a text file, or export data to a text file by using the Text ISAM, you receive the following error message:

Invalid setting in Excel key of the Engines section of the Windows Registry.
This problem occurs if both of the following conditions are true:
  • The DisabledExtensions value in the following registry subkey
    contains an extension that is five or more characters long.

    For example, abcde causes the problem if the registry value is the following:
  • Microsoft Jet 4.0 Service Pack 3 (SP3) or Service Pack 4 (SP4) is installed, or you are running Microsoft Windows 2000.
To resolve this problem, install the latest Jet 4.0 service pack. For additional information about how to obtain and install the latest Jet 4.0 service pack, click the following article number to view the article in the Microsoft Knowledge Base:

To work around this problem, use only the first four characters of any file name extensions in the DisabledExtensions registry value. For example, if abcde appears in the list of file name extensions
change the registry value to:!txt,csv,tab,asc,htm,html,abcd
