Here are the bese settings: I have windows 7-64bit installed, also drivers for smart card reader and ID card working perfectly, I can digitally sign PDF and other documents (pin code working, etc ...). In Thunderbird Security Device and Certificate detected (pin code asked). Still can not digitally sign email. Tested either 32/64 bit Thunderbird.
