Probably to just differentiate between architectures, i.e. "normal Intel", not IA64, not ARM, etc.

You could check if the QtWebKit "forward port" can handle your needs and whether it is available in 32 bit

This is unfortunately mostly a Google/Windows problem, i.e. Google not supporting this kind of build of the Blink Engine on Windows.
Also the reason QtWebEngine can't be built on Windows with other compiler than MSVC.

One option you could investigate is separating hardware access from UI.
E.g. running a headless program (child program or service) in 32bit mode for accessing the hardware and running the UI with 64 bit.
