1. Disconnect and reconnect the card reader

2 Internet Explorer: Add-ons

If the issue persists it might be caused by a program that influences the security settings in Internet Explorer. Please follow the steps below to locate this program.

  1. Launch Internet Explorer
  2. Click on the gear icon  (or the Tools menu) at the top right > Manage add-ons
  3. Under the drop down list Show, click All add-ons or Toolbars and extensions (depending on your version of Internet Explorer)
  4. Disable all the Toolbar add-ons (except the ones from publisher Microsoft, Isabel, Oracle, Adobe and Google). If you are unable to disable a toolbar, close Internet Explorer and navigate to the list of installed programs (to access press . In the Run prompt, type appwiz.cpl and press Enter) to uninstall the toolbar there.
  5. Try to log in again to Isabel 6. If you encounter the same screen, simply press CTRL + F5.

If the issue persists, verify if the toolbar that you could not disable is indeed removed from the Toolbars and extensions. A common add-on that also causes issue is SaveByClick, BrowseToSave/Browse2Save. Verify if they are installed by navigating to the list of installed programs (to access press . In the Run prompt, type appwiz.cpl and press Enter). They will be listed there.

3. Delete temporary internet files
4. Reset your browser

Verify the Internet Options > Connections > LAN settings. Copy all available information since this is required to connect to the internet.

After the reset of your browser, if you have copied some settings at the beginning of the procedure, you can now go back to LAN settings to restore them.
Verify if 'Automatically detect settings' is disabled.

Reset your browser.

Make sure you have installed the latest security patches in Windows and verify the following settings in Internet Explorer:

  1. Click Start > typ 'Control Panel' > Network and Internet > Internet Options > tab Security.
  2. Click on Trusted sites and set the security level to Medium-Low.
    Disable the option "Enable Portected Mode"
6. Software and hardware known to interfere with Isabel 6
  1. Check if there are specific security software packages installed (or any other programs that might interfere with the workings of Isabel 6) and adapt the configuration if necessary.

  2. Disconnect the Isabel 6 cardreader and reconnect on another USB. Try to login.
    If any other reader than the Isabel 6 cardreader is connected to the computer, disconnect it.
7. Network settings

Check the LAN settings:

  1. Click Start > typ 'Control panel' > Network and Internet > Internet Options > tab Connections
  2. Choose LAN settings > verify if 'Automatically Detect Settings' is disabled.
  3. If 'Use automatic configuration script' is active or if a proxy server is configured in the LAN settings, or if you use a firewall, verify with your IT or system administrator that your proxy and/or firewall are configured correctly.
  4. Click OK to save and close these windows.
  5. Close your browser and try again to login.
8. Run Isabel 6 as administrator

Right click on the icon of your browser in the start menu and select the option run as administrator.

If this solves the problem, your normal Windows user rights are not sufficient to use Isabel 6. Contact your system administrator to adjust these restrictions in the security or policy settings.

      • Use Microsoft compatibility lists
    5. Close all Internet Explorer windows, then restart Internet Explorer and retry.
  • If the issue persists or Compatibility View is already disabled (or not available), check the Document mode:

    1. Click on the Internet Explorer window, then press F12 to open the Developer Tools.

    2. In the Developer Tools window, go to the tab Emulation.

    3. Change the Document mode to Edge (Default) and close the Developer Tools again with F12.
