HASP key on ATL Web Service and Windows Vista / IIS 7

Question

Hi! I developed a ATL C++ Web Service on VS 2005 to access a HASP hardware key. This code works fine on Windows XP and IIS 6. When i try it to run under Windows Vista and IIS 7, the w3wp.exe process that is responsable to run the web service, crash with a access violation error. Someone had already this problem ? sugestions needed.

Thanks
