Cannot connect to database via ODBC. Error: Can not connect: 444 "HY000 [01000 The driver returned invalid (or failed to return) SQL_DRIVER_ODBC_VER: 03.80 HY000 [" | The problem may be caused by missing entries in the PATH environment variable. The variable might have been set by the driver installer and will be propagated to all newly-started applications (thus the third-party tools will be able to connect), but not to the windows services (regardless if they are restarted). Since BRIDGE services inherit the environment of the Console windows service, they also end up with missing entries. | Reboot after driver installation. |
