The error commonly happens if the computer has a power failure. It will corrupt the localsettings.xml

If you encounter the hexadecimal error follow these steps

  1. Browse to directory C:\ProgramData\Identicard  
  2. Look for localsettings.xml
  3. Delete the localsettings.xml file
  4. Try to login to Premisys ID. After you login back in the localsettings.xml file will be regenerated.
Please note the C:\ProgramData is a hidden system folder in Windows. You will have to enable show hidden folders in order to see this directory.
