However, if the software that is required to use a smart card in Windows is not logoed or is of a type that differs from a minidriver, such as a PKCS#11 driver, a custom CSP, middleware, or an ActiveX control, the automatic download option fails because Microsoft certifies only smart card minidrivers. Therefore, if the user inserts a card for which a custom CSP is not already registered, the user receives an error message that states that the driver software is missing for the smart card device even though the user can use the smart card through additional software that was installed on the user's computer from a custom installation.
- Click Start, type devmgmt.msc, and then press ENTER to start Device Manager.
- In Device Manager, right-click Smart Card under Other devices, and then click Disable.
- When you see a Smart Card dialog box, click Yes.
You must repeat these steps for any new smart card that you plug into the card reader on this computer.
