Question: what is the difference between office 365 32 bit and 64 bit?
Answer: Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes). ... The 64-bit version of Office may perform better in these cases.
