A smart card was detect but is not the one required for the current operation

"A smart card was detected but is not the one required for the current operation. The smart card you are using may be missing required driver software or a required certificate."

When a smart card name is displayed (e.g. "SmartCard-HSM")

• You are trying to create a container or certificate on a read-only card, or the smart card is full
• You are trying to create a container with the same name as an existing container on the card
• You are loading an explicit container that could not be found on the card — this can occur on cards where container names are volatile and the OS tries to reuse a container whose name has changed since it was closed

When the smart card name shows "Unknown"

A driver is missing. It may be a CSP or minidriver missing for CAPI, or a KSP or minidriver missing for CNG.

Solution: install the CSP / minidriver / KSP for your card.

Run certutil -scinfo to check the driver status:

• Verify the Card field is populated (not empty or "Unknown")
• Check that the minidriver DLL can be found (DLL not found = driver installation issue)
• Combine with Process Monitor to detect missing DLLs or registry entries
