That image is quite hard to see clearly, however it seems that you have the INSTALLATION EXEs for both Garmin USB Drivers and WebUpdater in the Garmin folder. Those applications need to be run to install their respective softwares, after which (if WU is installed to it's default location) there will be a folder "Webupdater" inside the C drive's Garmin root folder, i.e. you need WebUpdater folder with it's contents as a *sub-folder* inside Garmin folder. Also because you seem to have "Hide extensions for known file types" checked in Control Panel\File Explorer Options\View, it appears you may have named the BAT file as "2720update.bat.bat" or even "2720update.bat.txt" and the second won't work at all, although it should still run with that first naming but it won't be able to preform the task required anyway being as the Webupdater folder is missing.

Firstly, i'd suggest you uncheck that box in folder view so that you can clearly see the extensions are correct (*.img; *.exe; *bat). Type "Control Panel" in the Windows search box and uncheck as shown in the image behind the spoiler below, then click 'Apply':
