I have a Dell M6700 running windows 7 ultimate 64-bit. I have gotten my smart card to work with chrome, firefox, thunderbird, ie 32-bit, collabnet svn client 32-bit.
When I use ie 64-bit, it never asks me for my smart card's pin, and then just errors out. When I use svn 64-bit (collabnet or tortoisesvn), same thing happens.
I could use some pointers.
