Problems with KBC-Online for Business or Local? Discover our quick fixes.

What's the problem? 

The problem occurs after upgrading the Java plug-in (dated 16/04/2014). If you enter your PIN/password using the Shift key or Shift Lock, you probably see the 'Security software problem' alert.

The solution

1. If your PIN/password contain only letters, don't use these keys. You can also enter your PIN/password in lower case.

2. If your PIN/password contain numbers, use the numerical keypad, not the Shift key or Shift Lock key in combination with the numbers across the top of the keyboard.

If your keyboard does not have a numerical keypad – it's usually on the right of the keyboard –  change your PIN/password temporarily to a letters-only one.

How to change your password:

• Use Finder to go to the ‘Programs’ folder
• Open the ‘O4BMac’ folder
• Launch the ‘O4BMacControlPanel’ application
• Double-click ‘Change password’ and enter your password. You can then change the password to lower case.

Problem description

When you click the LOG IN button, you receive the message 'Security software problem. Security software is not working correctly; reinstall the software.'

Causes and solutions

1. Your browser : Using Safari? Close Safari and then restart it. Change the Safari settings
(Safari  menu > Change Safari settings > Make sure all check boxes are selected then hit 'Reset’.) Outdated version of Firefox? Make sure you are using the latest version of Firefox. 

2. Your card or card reader :

Unreadable card

There is an incorrect or unreadable card in the card reader. Use the correct card, i.e. your Isabel or e-Business card. Other cards, such as your bank card, will not work with the card reader.

Card removed from reader after clicking 

You removed the card from the card reader after clicking the LOG IN button. Leave the card in the card reader whilst logging in.

Remove the card reader from the USB port

Disconnect the card reader from your Mac's USB port, wait a couple of seconds and then plug it back in again.

3. Your security software installed on your Mac

Remove the security software and then reinstall it. Download and manually install the driver for your KBC e-Business Card.

4. Java

If you are using an older version of Java – on OSX 10.6 or lower – you will need to configure your Java preferences in sequence::

• version 1.5: 32 bits
• version 1.5: 64 bits
• version 1.6: 64 bits

5. Your bookmark


Do not use a bookmark to go to the KBC website. Try to log in using the button above.

6. Restart your Mac

Windows has recently been updated. As a result, the KBC card reader does not work for some users of KBC-Online for Business. The same applies for other connected USB devices.

Use this procedure to resolve this problem. (Dutch)

Running Internet Explorer 10 or 11 on Windows? If so, you first need to update the registry. That's easy to do using this tool.

Download and install the KBC security software.

If the download fails, right-click the link and select 'Save as'. Save the file on your computer and then run it.
