Hi,
If CreateInstall supports Microsoft Installer, then the best method is
to use the merge module we provide on http://odbc.postgresql.org/.
Failing that, check for the existance of
C:\Windows\System32\psqlodbc.dll and the registry key
HKEY_LOCAL_MACHINE\Software\ODBC\ODBCINST.INI\ODBC Drivers\PostgreSQL.
There are also registry keys under
HKEY_LOCAL_MACHINE\Software\ODBC\ODBCINST.INI\PostgreSQL, but it these
are missing but the other exists, then you have a problem anyway.
HTH, Regards,
Dave.
