'Smart card no more available' with ActivClient 6.1 + built-in reader

windows

Symptoms

Computers with a built-in CAC reader (some Gateway, some HP laptops) plus an external reader throw 'smart card no more available' on AC 6.1.

Likely cause

ActivClient 6.1 cannot juggle the built-in reader plus an external reader.

Fix

1. Upgrade to ActivClient 6.2 or newer. 2. If you must stay on 6.1, unplug the external reader and use the built-in slot only. 3. On certain Gateway laptops the card must be inserted upside down.
