No, it will only upgrade from an early revision - ie. 08.00.0101 ->
08.00.0400. Uninstall the old driver first, and then install the new one.

Why are they unable to connect? The driver is backwards compatible with
older servers, and the server is backward compatible with the older clients.

Dave,

When I uninstall the old driver and install the newer driver it is not
available in admin tools data sources as a driver to select from to
configure any type of DSN. In addition, when I have attempted to use the
newer MSI packages to install the ODBC it registers in the local machine
but not the current user. Any thoughts?

Thank you for your support.

Why are they unable to connect? The driver is backwards compatible with
older servers, and the server is backward compatible with the older
clients.

Those two statements seem somewhat contradictory. It always installs
itself on a per-machine basis so thats not surprising, but how do you
know it's registered for the current machine if it's not listed in the
DM dialogues?

Shows where under 'local machine'? The ODBC driver manager shows the
registered drivers in a single list so you cannot distinguish between
those registered per user or on the system. The *DSNs* are shown
seperately, but they're a different matter altogether.

No, that's why the change was made in a major version change.

If you're doing that sort of work manually you should really reconsider
your management methods - thats the sort of thing Group Policy is for.
Not that you should need to rename anything anyway.

So, please clarify - you uninstall the 8.0 driver:

- Does it get removed from the list of available drivers in the driver
manager?

- Is it still listed in the registry under
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI ?

You then install the 8.2 drivers:

- Are they listed under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI ?

- Are thy listed in the list shown by the driver manager?

OK - in that case, please remove the PostgreSQL key as well as the
value: HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers\PostgreSQL

As I said previously, it's not supposed to.

Did you copy the DLL from the installation directory? We intentionally
don't install into C:\Windows\System32 any more to avoid possible
conflicts with other software that might have installed SSL or Kerberos
libraries. Please uninstall the 8.2 driver, and remove any registry
entries for it that might remain (there shouldn't be any, but if you've
moved files around, that installer database will no longer reflect
reality so it might not fully remove everything), then try reinstalling
using the default install location etc.
