Problem

Remedial action

Windows fails to detect the module and launches a wizard instead

This indicates that you connected the module to the computer and turned on the power for the first time before you installed Chromeleon.

To resolve the problem, do the following:

Procedure

  1. Select Cancel to exit the wizard.
  2. Turn off the module and unplug the USB cable from the computer.
  3. Install Chromeleon.
  4. Reconnect the USB cable to the computer and turn on the power to the module. Windows will now detect the module and install the USB software for the module automatically.

Chromeleon audit trails include error messages that indicate interruption of USB communications, such as:

"Error receiving status: Error reading from <device name> @ USB <address>. The I/O operation has been aborted because of either a thread exit or an application request. The license is invalid."

Windows Application and System Event Logs might include error messages related to one or several of the following:

  • Chromeleon
  • The disk I/O system
  • W32time
  • Other functions

This indicates that the Instrument Controller PC entered Standby or Hibernate mode while Chromeleon was operating instruments and/or collected data.

Follow sections Disable Windows power management and Disable USB power management to disable (USB) power management.
