When trying to install a driver for your eMotimo TB3 or Dynamic Perception MX3 on Windows 8.1, you may receive the error message “The driver is not digitally signed”.
If this happens, you need to temporarily modify your Windows 8.1 settings to "Disable Driver Signature Enforcement".
Step 1 - Open the Windows 8.1 "charms bar" and click the Settings icon
Step 2 - Hold down the shift key and click the power icon
Step 3 - Hold down the shift key and click Restart
Step 4 - Choose Troubleshoot
Step 5 - Choose Advanced Options
Step 6 - Choose Startup Settings
Step 7 - Click Restart
Step 8 - Before Rebooting Windows 8.1 displays the startup settings. Select "Disable Driver Signature Enforcement" by pressing the '7' key on your keyboard.
After Windows reboots, you can install the driver without an error.
Once the system starts, you should be able to install the driver. When you see the warning screen, click "install this driver software anyway"
