You have started a session to use ALL In Response clickers or compatible eInstruction clickers, and get the following message:
"We cannot find any attached receivers. Please make sure the receiver is plugged in and click the re-scan button below."
I. Be Sure it's Plugged In
Make sure the receiver unit is plugged into an open USB port. If you have a receiver unit plugged in and still get the Re-Scan Receivers button, see Solution 2.
II. Check for Conflicting Software
The most common cause of this problem is that another software program has connected itself to the receiver and will not share it with ALL In Learning. Typically, closing any eInstruction Device Manager software solves the problem, but Smart's device manager can also be the cause.
- Locate the icon for the eInstruction (or Smart) Device Manager or Tools software in the system tray (bottom right of your screen). Depending on the version of the software you are running, it may have slightly different icons and names.
- Right-click on the icon and then select Exit or Close.
- Toggle back to your ALL In Learning response pad toolbar and click Re-Scan Receivers.
- You should be ready to go, and the toolbar will most likely look like this:
NOTE: eInstruction's or Smart's "Tools" or "Device Manager" software is often set to startup whenever you restart your computer. To avoid having to exit out of it after every restart, consider A) Uninstalling it, or B) Following the instructions in this link to remove it from your Startup folder and/or MSConfig settings, so it will only start when you manually decide to launch it:

III. Zero In on the Hardware
If you have access to another receiver and computer, trying your receiver on a different computer, and a different receiver (of the same type) on your computer can very quickly help you narrow down the problem.
- If your receiver works well on another computer and another receiver doesn't work on your computer, the problem is probably with your computer. If this is the case, move to the next section marked "Troubleshooting Your Computer."
- If your receiver doesn't work on either computer but the other receiver (of the same type) works on both computers, the problem is probably with the receiver. Please contact email@example.com for help, and include the details of what you've tried and discovered.
- If you don't have access to either another computer or another receiver, swapping what you can still be very telling. If your receiver works well on another computer, please move on to the section titled "Troubleshooting Your Computer." If another receiver (of the same type) works on your computer, please contact firstname.lastname@example.org for help, and include the details of what you've tried and discovered.
NOTE: RF receivers are matched to the clickers they shipped with. Avoid mixing and matching clickers and receivers in this process so you aren't inconvenienced unnecessarily or misled by the clickers that don't seem to work.
If this section wasn't helpful, or if you couldn't try any different hardware, move on to the next section.
IV. Troubleshooting Your Computer
If the section above helped you determine your computer is the problem, try these steps.
- Be sure you've thoroughly examined the above section on Software Conflicts, as this is the most common cause of problems and it's an easy solution.
- Restart the computer. It's amazing what re-initializing the OS can resolve!
- Windows Users: Go to your operating system's device manager (follow these steps to get to your device manager: http://www.computerhope.com/issues/ch000833.htm), and make sure the receiver is being recognized by your computer by unplugging it for 10 seconds and then plugging it back in - it should appear under the "Human Interface Devices" section and look normal (no alert symbols). If it does not show up in the device manager, your operating system doesn't know it's plugged in -- confirm that you are plugging into a good USB port, try different USB Ports, remove any USB hubs or splitters and plug directly into the computer, and try unplugging everything except for the receiver, and unplug your receiver for 10 seconds and plug it back in while watching the device manager list. If you cannot get the receiver to show up in Device Manager, please contact your school's IT staff as it appears there may be a problem with your computer's hardware.
