[Only registered and activated users can see links. ] both run fine for me using Win10 32 bit and 64 bit and even in Win11_x64 so the problem's elsewhere for you. Forget using the Win7 Notebook and just concentrate on the Win10 Desktop. Check that your Windows settings or antivirus program isn't blocking Updater.exe running in Win10, even try temporarily disconnecting from the internet and then turn off AV protection completely while you run Updater. Ensure you have the latest version of [Only registered and activated users can see links. ] too.

You can also check that the device is connected in preboot by opening Device Manager. Use Windows Search to look for it and set "View by:" to either Large or Small Icons in Device Manager. Watch to see if "GARMIN Devices" appears in the alphabetical list of devices after you connect the device while holding the screen. You should also hear the Windows 'duh-dum' connection tone if you have sounds enabled. Keep holding the screen and time how long it it stays in the list before it disappears because that's the period your Drive/DriveSmart stays in preboot. Whether that's 5 seconds or 30 seconds (i'm thinking it's no more than 10 for Drive series) that is the MAXIMUM time you have to properly establish a flash from Updater before the device drops preboot.

Like Updater, G7ToWin also only sees Garmin devices in preboot with Garmin USB Drivers loaded to the PC.
