Fundamental Application Service Creation Failed; hexadecimal value 0x00 is an invalid character line, Position 1. Unable to login to Premisys ID


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 the localsettings.xml file will be regenerated.
