64-bit Transition-- With this release, AutoCAD supports both 32-bit and 64-bit Windows environments. As a result, all drivers must be compiled in both 32-bit and 64-bit versions. Technical information on porting 32-bit driver code to 64-bit versions can be found in the ObjectARX 64-Bit Migration Guide.
