Important: To make sure that you have the best user experience, we always advise to use the latest version of the Isabel Security Components. Available here: Isabel - Download area

If the issue is not solved and you are an experienced computer user or the IT assistant of the person experiencing the problem, you can contact our helpdesk for the advanced troubleshooting described in the next steps.
  1. Go to Start > Isabel Services > Isabel Control Panel > doubleclick on 'Version'
  2. Check the values in the column "Reader Name" (1) and "Card ID" (2)

  3. Reader Name ACS APG8201 should appear in the list of readers and Card ID should correspond to the number you can find on your Isabel SmartCard (800...)
    1. If ACS APG8201 does not appear in the list of readers, follow this solution
    2. If you don't see your card ID, there is probably an issue with the Isabel SmartCard. If cleaning the chip does not solve the issue, contact our helpdesk.
  4. Right-click on the Isabel 6 login icon from your start menu or desktop and select Run as Administrator.
  5. Try to login in Isabel 6.
    If you can login as administrator, the Windows user rights are insufficient to run Isabel 6.
    Correct these limitations in the security or policy configurations.

  6. Check if there are specific security software packages installed (or any other programs that might interfere with the workings of Isabel 6).
    Adapt the configuration if necessary.
  7. Verify the settings of the proxy server and/or firewall.
    Adapt the configuration if necessary.
  8. Remove the Isabel 6 Security Components and reinstall the latest version via our download area.
