Can confirm that both of them work.
It seemed to do that on my XP32 machine as well, not sure what it is.
I've been running XP64 24/7 on my Sandy Bridge server since August 2019 and have yet to run into any major issues.
I have gotten MiniBrowser working on XP64 by renaming the missing SetProcessDEPPolicy function in MiniBrowser.exe and chrome.dll to a random existing function (in my case I used SetLastError) using PE Tools.
