Your device will be automatically updated to 64-bit if it meets the requirements.
Reasons to choose the 64-bit version
The 64-bit version is the right choice if you plan to use large files, if you have a lot of files, and if you have a computer that's running a 64-bit version of Windows.
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.
Reasons to choose the 32-bit version
The following computer systems can only install 32-bit OneDrive (check your Windows version).
-
64-bit operating system with ARM64-based processor not trying the ARM64
-
32-bit operating system with an x86 (32-bit) processor
