Fingerprinting the Windows architecture from a file on a remote system

This is a post followed with this one.

Similar situation to that of the article above – I would like to know if there is a way to know the architecture (x86 or x64) of a Windows system from A file located on a remote system. This assumes that I can only read files on a remote system and that I must deduce from it.
I would like to know as many windows versions as possible, but my specific use case is Windows XP.

design – What technologies should I use for digital fingerprinting? What development strategy should I use?

I am an online survey provider and, because of the nature of my business, I receive a lot of fraud and duplicates for my investigations, which I can not control with the help of cookie restrictions.

I want to implement digital fingerprint tracking so that I can track the uniqueness of the respondent and block unwanted respondents.

I want to know what technology should I use for this project (can handle 1,000 to 1,500 requests per second or more).
I also want to know what development strategy to use for this project.

So far, I've tried Fingerprint JS, Ever Cookie, but because of my traffic that's close to a million (1 million) a day, it can not work at the moment.

All kinds of suggestions and advice are welcome. If this is not the place to ask such questions, please let me know.
