Computer Problem: Cryptographic Services - Can not install PCSX2

When I try to install PCSX2 my computer will not let me because it tells me that it call not find a dll file and to make sure that the cryptographic services and cabinet are correct. I have never heard this type of terminology used before. I am using Windows 7. Can someone help me figure this out?

Thank you!

Can you post it what error / missing dll file?
