Unable to run and subsequently reinstall Navigraph Charts after I was prompted that a new update was available if I restarted Navigraph

I was in MSFS 2020 (Steam version) and fired up the desktop version of Navigraph Charts. A popup message appeared that there was a newer version that would be available to me when I restarted Navigraph - which I did. Unfortunately Navigraph Charts no longer worked! Once out of MSFS, I downloaded Navigraph+Charts.exe from the Navigraph website and ran it, but it failed indicating that it couldn’t find the uninstaller. I then ran Add and Remove Programs and tried to uninstall Navigraph Charts but that failed. I then - successfully - removed all the other Navigraph related apps, rebooted and ran Navigraph+Charts.exe again, but received an Installation Aborted message.

I have included screenshots of the Add and Remove Programs message window; the Navigraph Charts Setup window; and, the log file from the failed install attempt.

Hopefully this information will help in solving my problem.






Welcome back

I suggest a fresh start using exact procedure below , please :

  • Disable any Antivirus and firewall. Uninstall AV if needed.

  • Use only Windows Programs and Features to uninstall Simlink and Charts:

  • If they exist delete folders:
    c:\Program Files\Navigraph\Simlink
    c:\Users\username\AppData\Roaming\Navigraph\Charts c:\Users\username\AppData\Local\Programs\Navigraph Charts

  • Download and run free CCleaner to clean up your registry.

  • Download and install latest Charts to the default locations.

  • Download and install latest Simlink to the default locations.

If still an issue, please post latest c:\Users\username\AppData\Roaming\Navigraph\Simlink\logs\simlink_xxxx.dlog



I ran through all the steps described in your response to my issue, but still no luck with successfully installing Charts. Same issue(s) as before.

I cleaned up everything again after which I got brave and ‘interrogated’ the Navigraph+Charts.exe file with 7-ZIP and found and extracted the Uninstall Navigraph Charts.exe file. I ran that .exe, which appeared to run fine – at least there were not complaints or pop-up windows. After that I re-ran the Navigraph+Charts.exe file and everything worked, so I am back in business.

I’m not sure why running the Uninstall Navigraph Charts.exe cleared the logjam, but it did!?

Many thanks for getting back to me and for your excellent product.
