Re: Unlikely but…
Known supplier of certain powertrain components had a software tool that was 1) driver for the adapter that could talk to their control module on SAE J1939 (CAN bus), 2) live telemetry from said module, 3) reconfiguration of module (must have supplier's secret engineer password), and 4) help files to understand the internals of the main product to which the control module was connected. These help files included some Flash animations of the internal fluid flows of this product, and the user could select views of various product modes to see how the flows were affected. I can't remember if the Flash diagram was linked to telemetry in any way, or if the main program used Flash for its gauge animations -- the main point is that any laptop that contained this program also HAD to have Flash.
I was keeper of that special test laptop (along with some other test assets including other laptops) for about 3 years, which I updated diligently (Windows, Flash, other things) even though it was primarily air gapped (physical wi-fi radio switch, but no other lockout). That was about 10 years ago, and I don't know what their software requires now.
