Error description

  • PComm V6 has worked on pre-Win 10 installations. However, on
    Win 10 I am getting an exception from PComm
    (interop.AutSessTypeLibrary - System.AccessViolationException -
    "Attempted to read or write protected memory." Calling
    '_Session.autECLPS.WaitForString("login:", 0, 0)'. I have
    installing fixes for V6 and I have even tried a trial version of
    V13 - both still have the same issue.
    
    I see this in the Application Event log.
