Wow, I did not even realise there was a 32 bit version of Win10. Anyway, if you are running on a 32 bit system due to hardware limitations, your system falls well short of ArchiCADs minimum requirements...

when installing the program, it reports that windows is not supported
Thank you for the question and I am sorry to hear about the issue!
