Windows 7 users may experience one or more of the following issues with Attendant when using the TimeKeeping Systems USB cable and Direct Downloader:


Related issues when Attendant is unresponsive:


Rebooting may resolve the issue temporarily. No error messages or Event Log entries are returned.


The unresponsive behavior does not occur when using the Serial cable.





Verify that only one User Account is logged in to the PC. Multiple active User sessions (which occur when using the Switch User command instead of the Log Off command) may result in multiple running instances of Attendant.exe, causing a conflict with the active User session's instance. Using the Log Off command instead of the Switch User command is strongly recommended. NOTE: Rebooting the PC resolves this issue because all User Accounts are shut down due to the reboot.


Confirm Prolific USB driver version

Confirm that the correct version of the Prolific USB-to-Serial COM Port driver is installed:


If the problem is not resolved, see section Use the Serial Cable.



Use the Serial Cable

If a serial port is available on the PC, use the included Serial cable to connect the Direct Downloader to the PC. Follow the steps in Adding a Downloader to add the Downloader to Guard1 Plus. No further action is necessary.


If no serial port is available, see next section Install Hotfix.


Install Hotfix

If the Prolific driver version is correct and no serial port is available, a Hotfix has been created that may resolve the issue.


  1. Log in to the Guard1 Plus PC as a Local Administrator.
  2. Download the Hotfix setup file (OCXHotfix20120413.exe) to a folder on the Guard1 Plus PC.
  3. Close Guard1 Plus and Attendant.
  4. Open Computer and browse to the folder where you downloaded the Hotfix setup file in step 1.
  5. Double-click the file OCXHotfix20120413.exe. Click Yes at the UAC prompt if it appears.
  6. Follow the prompts to install the new OCX file. Click Finish when the process is complete.
  7. Launch Attendant and monitor its behavior.



If the problem continues after performing all the above steps, you may have to purchase a USB Downloader to replace your Direct Downloader.  Please contact Technical Support.
