Unreachable Roles Table. It is not possible to edit your security settings
Problem
You get this error when using the Application Security Wizard in Iron Speed Designer:
Unreachable Roles Table
It is not possible to edit your security settings because your Roles table is currently unreachable.
This error can occur when your Oracle database DLLs are not properly registered.
Solution
Re-register your Oracle DLLs, e.g.:
regsvr32 C:\oracle\product\10.2.0\client_1\BIN\OraOLEDB10.dll
