Is ActiveX anything to do with DirectX? There is a tool that can interrogate the state of health of DirectX on a PC; I wonder if there is anything similar for ActiveX? Sounds like a good line of Google enquiry.
ActiveX is just a way of integrating 3rd party software into the user interface of any application. Depending on how the TWAIN driver was put together, it may or may not use any ActiveX controls.
Since these are typically 3rd party components, it is possible that some other software upgrade can cause problems.
Unfortunately there is no easy way for you to know what may or may not have happened here, except try to think of what kinds of changes you have made to your system since it was last working properly. Any un-related updates you applied or software you have installed.
In the end such a list might offer some clues, though ultimately the scanner manufacturer is the only one that can confirm or deny any potential conflicts for you.

“eradicate any driver specific presets from your computer”
Not sure what you mean by this. Can you elaborate a wee bit please?
I was referring to any settings files or registry entries that are not typically touched by the un-install programs. Usually session settings are stored and restored from either a configuration file or a registry section and they often survive the process of re-installing. If unexpected values are poorly handled by the driver in question, then it might be helpful to manually delete anything you find left over after an uninstall.
I have no specifics for you, since the implementation of this is completely up to the manufacturer.
