I have been getting a lot of fatal errors when using ADT the messages I have received range from 'Application failed to Initialize Properly' to 'Unhandled Access Violation Reading'. I am currently referencing a lot of material from other Autocad software (BS Link and Autoplant) with the current object enablers loaded. Could these be causing a conflict? or could this be a hardware problem (my machine is quite high spec and exceeds the Autodesk recommended spec). Would the current ADT service pack stop these errors? Please can anyone help.
