Issue with HASP for Win7 64bit

Hello Techyv Friends,
I installed HASP driver successfully in my Win7 32bit and is supporting fine. But when I tried the same in Win7 64bit, It says it installed successfully but it doesn't see the HASP device, Is there any issue with HASP for Win7 64bit. Please guide me to overcome this issue.
Thanks,
Young Hern
