    Hello,

    An issue reappeared with one of our clients, this driver C:\WINDOWS\system32\spool\DRIVERS\x64\3\OKSO_UM.DLL is causing Parallels to crash.
    When renaming the .DLL-file and rebooting the pc, it works again like a charm.
    But whenever a new update of that printer comes through, it's the same issue.

    Tsclient version is: 17.0.21472.0

    Thank you for looking into this.

    Regards,
    Dein

    It is a bit strange that you are permanently renaming the dll and the printer that should be using it still works fine.
    Maybe the printer (which you did not mention by name) is not really being used and the driver can be removed from the system?
