If Win Serviceses running under 64bit or 32bit

My team is developing an application containing Java and C++ components.    Testers need to verify if these components are running under 64bit within Win7 64bit, Window Server 2008 64bit OS.   In Win7 OS 64bit, I can see our services under “Window Task Manager”.     How to verify, if these services are running under 64bit?

Wait, what does that service do?
Doesn't it log informations somewhere you can see?

You will know it's working by the same way you do in any other system.
By watching the outcome/results.

If you are a testing engineer, then it's a bit more complicated.
But as i can see, you aren't.. so simply look out for the results and you will see if it's working.

If you built the application in 64-bit then the program will run in 64-bit. Where is the program installed? C:\Program Files\ or C:\Program Files(x86)?  If the application functioning?

32-bit programs need to be installed in the (x86) folder and\or run under the WOW64 folder

When I open "Windows Explorer", I can see Program Files (x86).  What do you mean run under the WOW64 folder?   How can I see this folder?

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Is your application currently working?

Program Files(x86) is where 32-bit programs must be installed to work.

WOW64 folder http://en.wikipedia.org/wiki/WoW64

Yes, they are running as windows services.    I can see our services under “Window Task Manager” under the "Service" tab.   How to determine from the "Windows Task Manager", are these 64bit application or 32bit application?
What are those services for?
If they are at the task manager, they are working, at least they are executing something.
But just with that information, it's not enough to determine if they are working correctly.
Tell us what are those services supposed to do and then we'll tell you how to determine if they are working correctly.

If the application was programmed for 64-bit  then the application or service is running 64-bit this is a programmers question not an OS
