ODBC Driver Setup

I work on an application which uses odbc to connect to a MS Access 2.0 database.  The setup for my application adds the DSN to the odbc.ini file, but in most cases, the MS Access Driver (16-bit) is not present on the machine, so needs to be installed separately.

This is usually no problem, but on one particular client's machine, the driver refuses to be installed.  The install proceeds 'normally', but when the 'Data Sources' window appears, the MS Access driver does not appear in the 'Drivers' window.  The DSN for my Access DB appears in the Data Sources window (because it was manually added to the odbc.ini file during my app's install), but when I click on Setup I get the message "The setup routines for the Microsoft Access Driver (16-bit) ODBC driver could not be found.  Please reinstall the driver."  When I close the Data Sources window, a message says that the driver was installed successfully, but no ODBC icon has been set up in the Control Panel (as should happen).

I have tried installing the driver in this way a number of times, even in Windows 95 'safe mode', but the result is always the same.  The actual 16-bit MS Access driver, odbcjt16.dll, is in the windows\system directory, so it seems like it has been copied correctly.  The only other thing I can think of is that one or more Windows components are missing, which are needed by the ODBC Manager, but I don't know what these components may be.  I haven't gone so far as trying to reload Windows, and would prefer not to if there is another solution.  I have tried MS Support Online, but couldn't find anything to help. . .

Sometimes the ODBC Driver Manager itself has bugs.  This is the program that allows you to set up and manage your DSNs.  We have found that some bugs are solved by udpating your client system to a more recent version.  For instance, we had some annying problems with the ODBC 2.5 driver manager that were only fixed by upgrading the ODBC Driver Manager to version 3.0. To see what version you have, go to the about box on the ODBC Data Source Administrator panel (what you get right after you double click the icon)  If it's below 3.0, I'd say upgrade, then uninstall/reinstall  your access driver.

I think you're talking about the 32-bit ODBC Manager - the 16-bit Manager doesn't even have an About, but I found the version from the properties on the odbcadm.exe, which is 1.05.0916.  According to MSDN, the latest version of the 16-bit ODBC Manager is 2.0c (the latest version of the 32-bit is 3.0, though I think 3.5 is in beta).  I actually have version 2.10 (?) on my machine (not the client's machine), but I don't have the setup disks for it.

Are there any other factors (eg. Windows components) which may affect installation of odbcadm.exe?
