IMPORTANT NOTE: On the day and time selected in the Internet Update window, ensure the following:

•	You must be logged on to your PC

•	Your PC cannot be in standby mode

•	Your PC battery must be fully charged

Go to Start ->Settings ->Control Panel ->Power Options and ensure that your "System Standby" and "System Hibernate" settings are set to "Never" on the day and time you have scheduled an Internet Update. Failure to do this could cause the Internet Update to fail.

If the PC is connected to the internet, IDSS will be sent updates through the internet.

NOTE: The update process may take several minutes.

If the PC is not connected to the internet on this day and time, you will receive a pop up message stating that the PC is not connected to the internet.  You will still be able to open and use IDSS.

At any time, you can open the Internet Update configuration window and click the Check Updates Now button.  If you are connected to the internet, IDSS will check for updates and download them to your PC.

Mandatory Updates

A few times per year, you will be required to update IDSS with mandatory updates that are available.  If you have been receiving regular IDSS updates, you will not see any interruption in your IDSS use. If you have not been receiving regular IDSS updates, when a mandatory update is available and you launch IDSS, you will be reminded to connect to the internet an perform an update.

Manual Updating:

1.	Connect to the internet.

2.	Launch IDSS (double click on the IDSS ICON).

3.	Click on the Internet Update ICON from the IDSS Main Screen. An Internet Update Box will appear.

4.	Close out IDSS (click on the orange X in the upper right corner of IDSS) if opened.

6.	If no updates are available, then text will appear saying "There are no updates to download".

7.	If there are updates available, the updates will automatically be loaded to the PC after you click the Check Updates button.

8.	After the updates have been downloaded to the PC, click "Install Updates". The updates will then be installed to the IDSS application.

NOTE: If you’re loading Setup Disc Version 1.0.0, you will need to check for updates TWICE. This is because there was a fix to the IDSS Internet Updater, which cannot be loaded with the rest of the IDSS fixes. So, check for updates twice when initially updating IDSS from the Setup Disc Version 1.0.0.

Automatic Updating:

There is an option to have the system automatically check for updates and install them once per week or everyday at a specific time. This cannot be turned OFF. In order for this feature to work properly, follow these guidelines:

1.	The PC must be turned ON.

2.	IDSS should be closed, but this does not matter as if your using the system as it will prompt you to install the updates by first closing IDSS. You can also install the updates at a later time (box will reappear each time you launch IDSS until the updates have been installed).

3.	The PC CANNOT be in standby or hibernation mode.

4.	You must be connected to the internet.

5.	If the PC was turned OFF, in standby mode or hibernation mode at the time that was set to automatically check for updates, the computer will not check for updates until the next time its scheduled. So if IDSS updating is set for 10pm every day and at 10pm the PC was off, the next time IDSS will check for updates is 10pm the next day.

If the above 1-5 is satisfied, IDSS with automatically download the latest updates AND install them to the IDSS application.
