Unable to load installable ISAM
Can't load mspdox35.dll (error code=126)

Error while configuring ODBC drivers!
The configuration of the ODBC Microsoft Paradox Driver (*.db) driver failed.

  • You did not install the Paradox ODBC driver, included in the Microsoft Office 97 Data Access Pack, on this computer.

  • Install the Data Access Pack included with Microsoft Office 97. To do this, run the file Dataacc.exe, located in the \ValuPack\DatAcc folder on your Microsoft Office 97 compact disc.

    Once the Data Access Pack is installed, the Setup programs for Microsoft Office 7.0 and Microsoft Visual FoxPro 5.0 should work correctly. -or-

  • Before running the Setup program for Microsoft Office 7.0 or Microsoft Visual FoxPro 5.0, rename the following files in your Windows\System folder: 
          Msjt3032.dll

MORE INFORMATION

Microsoft Office versions 7.0 and 97 and Microsoft Visual FoxPro 5.0 install a set of database files, known as Jet files, on your computer. Jet files are designed to be used by any program that works with database files.

Microsoft Office 97 behaves differently with respect to Jet files than Microsoft Office 7.0 and Microsoft Visual FoxPro 5.0:
  • By default, Microsoft Office 97 does not install the Paradox driver: if you want the Paradox driver installed, you must install the Data Access Pack. This differs from Microsoft Office 7.0 and Microsoft Visual FoxPro 5.0, which automatically install the Paradox driver.
  • Microsoft Office 97 installs a newer version of the Jet files than the versions installed by Microsoft Office 7.0 and Microsoft Visual FoxPro 5.0.
  • Some Jet files have changed names from one version to the next: specifically, the Paradox driver's name can be either Mspdox35.dll or Mspdox32.dll, depending on which version of the Jet files is installed on your computer.
Because of the change in behavior with respect to the Paradox driver, the change in versions of the Jet files, and the change in file names, you may encounter problems when installing programs that use an older version of the Jet files, such as Microsoft Office 7.0 or Microsoft Visual FoxPro 5.0, after installing programs that use a newer version of the Jet files, such as Microsoft Office 97. Note that you will encounter problems only when you install an older program after you have installed Microsoft Office 97.

To prevent problems from occurring, use either of the workarounds shown in the "Workaround" section.
