This problem only affects early versions of the InterBase ODBC driver. The licenses for these versions are case-sensitive and version-specific. You need to enter the license key in the same case as the one we emailed to you. To check, examine this registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft\IB6
–Or–
HKEY_LOCAL_MACHINE\SOFTWARE\Easysoft\IB6U
If necessary, edit the license key in the registry.
