Make sure your computer meets the minimum system requirements for running Autodata CDa3.

Because CDA3 is a standalone, offline version of Autodata, it is no longer actively supported or updated by the manufacturer. If these technical fixes don't work, most shops now transition to Autodata Online

A "Runtime error 217" can sometimes be a symptom of a larger problem with your Windows system files. You can use built-in Windows tools to scan for and repair these files.

CDA3 uses a security license system. If the Sentinel driver is missing or the emulator isn't running, the software will crash.
