The FireflyPro software installation includes two main components: The FireflyPro application and the device driver that allows the PC to recognize and control the Firefly device. The error message can be due to one of the following:
1. You do not have administrator privileges on the PC. Please re-install FireflyPro as an admin.
2. For software versions prior to version 1.50 – You may have accidentally installed the DE500/DE501 or other wired device software instead of the DE550/DE551 or other wireless device. Please download our new software version HERE. Save the file on your computer and install it by double clicking the file and follow the installation screens.
3. You plugged the wireless receiver in before installing the FireflyPro software. Please remove the receiver and install the software first.
4. You plugged in the receiver and immediately launched the FireflyPro software. On some computers (when you plug in the receiver for the first time) it takes about a min for the PC to recognize the new device and associate the driver to it. Please remove the receiver, plug it again and wait for the PC to recognize and install the device. Then launch FireflyPro application.
