I've a Xerox DocuColor 250, and windows 10. I'm trying to fix a problem that will crash any program when I go to printer preferences. The strange thing is that: if I open the control panel, printer preferences works good whitout any problem. But if I open printer preferences from for example Word the program will crash and close. On the event viewer I see:

  • The module that generated the error: harmony10.dll, version: 2.6.102.0.
  • The path: ": C:\Windows\system32\spool\DRIVERS\x64\3\harmony10.dll"
  • The error offset "0x00000000000f5dc0"

How is possible that the same thing on the control panel won't crash but with a program it crash with this error?

If the problem won't solved with some windows-tricks, how can I track and debug a program and check what thing don't work and trying to "hack" the dll to bypass the error?

Delete all software associated with the printer, open the command line and execute the printui /s command. Next, look for your printer and remove the driver completely. then install driver into printer disk or download here http://www.support.xerox.com/support/docucolor-240-250/downloads/enus.html?operatingSystem=win10

Also, try to open a command prompt on behalf of the administrator and enter:  

net stop spooler
del %systemroot%\system32\spool\printers\*.*
net start spooler
exit
