Google analytics > Technology >Browser and OS 64/32 bit

Trying to identify if it is worth continuing suport for the 32-bit OS for a desktop applet. Was hoping to get some idea of current OS use on the web portal where applet is downloaded from. Does anyone know if there is a way to see the OS breakdown by 32-bit vs 64-bit? I feel like this was available a while ago but now cannot find it anywhere.
