Pensando di far cosa utile, riporto la procedura trovata in un forum (forums.gpsreview.net) che permette di ridare accesso ad internet al programma di cui sopra.
Qualche tempo fa, non so per quale ragione, alla connessione del navigator V oppure al tentativo di avvio del programma mi appariva il seguente messaggio:
"Garmin Express can't open because the Internet connection is being blocked. Try disabling your firewall and proxy settings and open Garmin Express again."
Ecco la soluzione:
In some cases depending on how the security software is setup along with User Account permissions can cause issues with what has been described in various posts. One thing you can try is forcing access to allow the Garmin Core Services to be allowed through to the internet. These steps may help correct some issues.
1. Press the Windows key+R
2. Type "services.msc" and press Enter
3. Locate and right-click Garmin Core Update Service
4. Click Properties
5. Click on Log On tab
6. Select This account
7. Type "Network Service" in the Account field
8. Remove all text from both password fields
9. Click Apply, then click OK on the next three prompts
10. Right-click Garmin Core Update Service and Click Stop
11. Right-click Garmin Core Update Service and Click Start
If you have tried the above steps and nothing changes, and you have logged in as an administrator account some third party program or feature on your computer is blocking the Garmin Express software.
