Tactix 7 can't be found by Garmin Express (PC)

Hi, I've recently bought the Tactix 7 AMOLED watch (brand new) and installed the latest Garmin Express software from the official site. Followed all the instructions and installed it on my laptop (Windows 10 Pro N). The issue is that the watch is not recognized either as a storage nor as Garmin device according to the USB settings (System > USB Mode). Not appearing in Windows Explorer or Express. I've tried with my Instinct 2X Solar Tactical Edition and works like a charm but Tactix...not recognized at all. I've tried all that I could find on internet: Reinstalled Express, changed cables(all Garmin proprietary that come in the box), ran Express as administrator, restarted the PC and also the watch. Nothing helps. Still, the Instinct connects without ANY problem. This is very disappointing. Kind regards and thank you, Martin
