To confirm that your OS is 64-bit, use the command [wmic os get osarchitecture] in an elevated CMD (Run CMD as administrator). It should say "x64-based PC". To check the current CMD version, type [look] and look for "x64" next to the version number. If it says "wow64", it is the 32-bit version.

You can try sizeof(char*) , in general the pointer-to-char has the machine-size. If it's 8, then your machine is 64 bit, if 4, then 32.

The easiest method to find out if a DLL, UFL, or EXE is 32 or 64-bit is to open it in Notepad or another text editor such as Notapad++.

Reasons to choose the 64-bit version

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).

You can't install 64-bit Windows on a 32-bit machine. It won't install, and if you hack it somehow to install, then it won't boot after the install has finished. It is possible that the previous OS installed on the machine was a 32-bit OS version and that is why you think the machine is 32-bit.

A 64-bit processor can hold more computational data, including memory addresses, than a 32-bit processor, allowing it to access over 4 billion times the physical memory. The 32 bit OS, as its name implies, can store and handle less data than the 64-bit OS.

You can't. There's no way to change the "bitness" of any version of Windows from 32-bit to 64-bit, or vice versa. The only way to can get what you want is by doing a clean installation. What e-mail program is this?
