Received STATUS_OBJECT_PATH_SYNTAX_BAD for ZwOpenKey

In my WDF driver, we are using ZwOpenKey() API to open a registry key.

This API works perfectly fine in our 32 bit Windows7 same driver,

but for 64 bit driver we got STATUS_OBJECT_PATH_SYNTAX_BAD error.

Can someone please help me out in finding out the issue for 64 bit Windows 7 driver?

What is the UNICODE_STRING value you are passing to the API?

Thank you Doron. It was indeed the UNICODE_STRING string name which was causing the issue. The complete registry path was not being copied to the UNICODE_STRING.
