In SAP system goto T code ST06 and click on -> Detail Analysis Menu -> Click on H/W info and serach for kernel you will find your kernel is 64 bit or 32 bit.

SAP Note 931024.

You can find the bit level as follows,

In Unix/Linux, The flovour might be different

At sap level when you execute, SMICM tcode, you can check the bit version
On windiws systems, on the my computer when u right click-->properties, you can get the info.
If you want to know which flavour it is, execute the command "file disp+work" at os level in the kernelpath like,
abcadm 44> file disp+work
disp+work: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.4.1, dynamically linked (uses shared libs), not stripped

x86-64/x64/x_x64 all r related to 64 bit versions

In my Windows system My Computer --> Properties shows:
Windows Server 2003 standard x64 edition.

The SMICM T-code shows:
Internet Communication Manager Version 7.00, multithreaded, Unicode, 32 BIT.

And the kernel path is ...exeuc NTI386>

Does this mean the SAP kernel is 32 bit and the OS is 64 bit and while installing SAP, the application was installed using 32 bit option on 64 bit OS?
This system was installed by somebody else.

For Windows box, you can check in another way, that is
Make remote login to that system then, START-->programs->accessories-->systems tools-->system information. you will get the bit version.
