Hi Simon,
Welcome.
Try restarting Windows, disabling Antivirus then :
- Use Windows to uninstall Simlink and Charts. Specifically see FAQ - Charts desktop installer fails immediately
- If they exist delete folders:
c:\Users\username\AppData\Roaming\Navigraph\Simlink and c:\Program Files\Navigraph\Simlink and
c:\Users\usernamei\AppData\Roaming\Navigraph\Charts and c:\Users\username\AppData\Local\Programs\Navigraph Charts - Download and install latest Simlink and Charts .
- If still an issue, as a test please run Chrome as your default browser
- If still an issue,please upload latest dlog and log from c:\Users\username\AppData\Roaming\Navigraph\Simlink\logs
Cheers
Ian
