ISAM drivers are used by Access to update file formats other than its own. If the path of the ISAM driver in your Windows Registry is not valid, or if the ISAM driver does not exist, the problem may occur.
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To correct the problem, you can try to register the file manually or you must correct path name errors in the Windows Registry, and then install or replace the problem file. To do this, follow these steps.

2. Use Microsoft Windows Explorer to search for the file.
3. If the file is found, record the path name for the file. If the file is not found, go to step 13.
4. Open the Windows Registry Editor.
5. Locate the registry subkey that is described in the table, and then check the path name against the actual path name. If the registry key does not exist, go to step 8.
6. Correct the path if it is incorrect. Continue these steps if the path is correct.
7. Close Registry Editor.
If you changed the path, repeat the process that produced the original error.
8. If the error persists, try to manually register the file by using the Regsvr32.exe utility.
The Regsvr32.exe utility is an application that is used to register DLLs and ActiveX Controls in the Windows Registry. You can use this file to stop the issue of mismatched .dll files. To re-register your .dll files by using the Regsvr32.exe utility, go to the next step.
9. Verify that the Regsvr32.exe file is in the system folder where Windows is installed.
For example, the Regsvr32.exe file is typically found in C:\Windows\System or in C:\Winnt\System32.
10. Click Start, and then click Run.
11. In the Run dialog box, type the following command in the Open box.
