When Lumi is running, the title bar in PowerPoint should list a meeting and a session, for example: Presentation1 – Meeting: Default – Session: Initial Session
All of the below checks are done in the “Lumi Viewpoint” ribbon menu in PowerPoint (unless mentioned otherwise):
Check the receiver icon - does it say "Receiver Out"?
If it does, check and (re)start the service:
- Press the Windows key on your keyboard
- Type services.msc
- Click the icon labelled “services” that appears below the search box
- Ensure that the “IML Click Hub Service” is running (the “Status” column will show this)
- If it’s not running right-click the service and click “Start”
- If it is running, try restarting it by right-clicking it and clicking “Restart”
- If you’ve (re)started the service then you may also need to restart PowerPoint
Check the meeting icon - does it say "No Meeting"?
If the icon text is “No Meeting” then you could either:
- Try to open an existing meeting (click the meeting icon and then click “Open Existing”. This will give a list of meetings and you can select the appropriate one
- If it doesn't show any meetings, you can create a new meeting (click the meeting icon and then click “Create New”) – the session is automatically created
Suggestions from Lumi Support:
When starting up your laptop if you leave the Receiver unplugged it will allow more time for the Lumi services and Click hub services to kick in first as they are required for the software to then find the USB receiver and validate the licence.
If the services don’t start or you see ‘No Hubs’ you can manually restart them by going to:
- Close PowerPoint
- Windows Menu search bar and type Services
- Select the link that has two cogs
- A new window will appear and you will have to scroll to IML Click Hub, right click and select Restart. This service should say Started and Automatic by default, if it doesn’t then right click and change this in the Properties
- Then scroll to Lumi Services (or IML if running 4.8 or lower), right click and select Restart. This service should say Started and Automatic by default, if it doesn’t then right click and change this in the Properties
- Re-open PowerPoint and the No Hubs message should have disappeared.
If No Hubs occurs on a regular basis then it may be due to Microsoft .NET framework slow start up on the laptop which stops Lumi Services from starting and running. The solution we provide is to run a registry file on the machines allowing longer for Lumi Services to start up. This is not a 100% guaranteed solution but is less likely to hit the issue.
Click USB Receiver
When plugging in a Click USB receiver after boot up it will look for the device drivers, firstly by searching Windows Updates then locally on the machine. This may take a little while but if you have Hardware notifications enabled then you can skip searching Windows Updates by pressing the link in the pop up message which will then force it to look locally speeding up the process.
Once your receiver has been validated whenever you plug it in it should automatically be licenced but will display Devices (0). Handsets are sent out preconfigured and once a response is received by the receiver this display will update.
If your receiver isn’t automatically licenced double check the licence .xml file can be seen in the folder C:\Users\Public\Documents\IML\ViewPoint\Licences. This file should never be renamed as it will then become corrupt. Lumi can re-issue the licence if required.
If you are not getting a response from an IML Click handset when the USB receiver is in and licenced it may be due to either the handset being out of range or low battery. The range of the receiver is 45 metre radius from the laptop. Low battery’s will be evident if your press a response on the handset and no LED lights up or if you see 4 short red LED flashes. You can test the handset in IML Click system manager by pressing a button which will then populate the window and tell you about the device, ie Device name, channel, mode and battery level.
