Can you install a service in system32 or sysWOW64 directory and still pass Windows 7 Software Logo Program?

We are trying to certify a program for Windows 7 logo and we have a third party vendor which is providing a service for our application. their documentation and support crew is adamant that the service must be installed and run from the system32 (or sysWOW64 for 64-bit) directory. The Microsoft documentation states that you should...

Never write directly to the "Windows" directory and or subdirectories. Use the correct methods for installing files开发者_开发知识库, such as fonts or drivers

our vendor says that services are fine also. Does anyone have any experience with this? Are they correct? Can we logo our app if we put a service in system32?

My understanding is that you will not pass any logo testing with those conditions. You can apply for a waiver, and may be able to get one. But, you'd (actually your vendor) better have good reasons why their service needs to be installed into either of those directories. I cannot think of a reason, but that doesn't make it so.
