When I try to use smart card on Windows Vista Business 32bit I get this message: "The card is being shared by another process. However, the card is not the one being requested, and cannot be used for the current operation." There's an Microsoft article http://support.microsoft.com/kb/955548 which describes error and hotfix download. I have tried hotfix but it won't install since it applies only to Vista SP1 and I have Vista SP2. Can someone please help how to solve this problem?
