Why cant I load a driver from a local directory?

I do a scH = CreateService() and get a serviceHandle successfully. Using that serviceHandle I start the service and that passes when the 8th parameter to CrestService() i.e., ServicePath name points to "....system32\drivers" but fails when it points to a local directory like c:\users\Administrator\Myapp. Question is, is there a rule that the drivers have to be loaded from the system32 or SysWow64 folders only and should not be done from any random folder? In other words can drivers be loaded from folder or they have to be in system folder?

Please ignore this issue. The program did work on other systems without any problems. The system where it was failing I was told has some other OS related issues. So the answer to my questions is "Yes it can be done". Thanks to Rajanish.
