Hi,
When I update Navigraph Charts on 7.7.0, i get a message error after i start Navigraph like the following screenshot :
I use Windows 11 and the last version of Navigraph worked well !!!
Can you help me ?
Thank you
best regards
Hi…,
Welcome.
Does a restart of computer help?
Otherwise probably quickest to start from scratch with latest Charts and Simlink (assuming you have and want Simlink 
) . Please disable any Antivirus and Firewall.
In Simlink Plugin Settings uninstall Simlink plugin from your FS , then completely uninstall Simlink and Charts using Windows Programs and Features exactly as under .
If they exist delete directories
c:\Users\username\AppData\Roaming\Navigraph and c:\Program Files\Navigraph
Then download and install latest Simlink and Charts Desktop using the default prompted locations.
You should be advised of Simlink being installed into your FS (for non MSFS) .
Restart computer.
Please let us know how you get on.
Cheers
Ian
Hi,
In which country are you located? Can you access google.com in a regular browser?

I have already tried all your advices but nothing works
By chance, i have downloaded old version (7.6.0) whose works well until i close him and program disappear by himself…
Seems to be resolved with 7.7.1 version 
See video : Navigraph problem seems to be corrected - YouTube
Yes we issued a new updated earlier today with an improved online check mechanism. Glad it works better now!
