How to handle Incompatibility of Firefox and Gpj , JCmanager and GPshell?

Question

I have an ACR38 smart card reader.When the Firefox is Open in my computer, I can't use my smart card reader via gpshell , Gpj and jcmanager!! and when I close Firefox and kill it's process in "Windows Task Manager" everything will be solved! The question is, How I can have both of these softwares open simultaneously? Thank you.

Note : the error message that I receive of the gpshell / gpj and jcmanager is something like "The reader is in use by another application!!" I'll be post a picture of error tomorrow!

Answer 1

You've installed a PKCS#11 module in Firefox that requests exclusive access to the reader. Either remove the PKCS#11 (also known as cryptoki) dll or configure it is such a way that it does not use exclusive access (in the PCSC layer).
