Navigraph hub stopped working

Until today, Navigraph Hub has simply worked without any issues. I usually check it every couple of days to ensure that all the Navigraph hub is up to date for MSFS2020. Right now it showing a blank screen. I uninstalled the app and then downloaded it from this site and tried re-installing it without success. I looked at the FAQ and went through the files as suggested. Still no luck. I think that I have attached some snipped files of the permissions and I can’t see any difference from the ones you suggested in the FAQ.I haven’t tried running MSFS yet - but I will do so. I use the navdata for PMDG products and the CRJ. Any help appreciated.

Hi…,

Please try steps at Blue screen - #2 by skysail

Cheers
Ian

Ian:
I didn’t realize that support is only available during weekdays - I would have been considerably less grumpy. I’ll try your suggestion below.

Attached, please find the main.log file

Ian:
This notification has started showing up as well. Under the appdata file, there are several folders under navigraph hub. other than the log files, I have tried to delete this folder and I get the following notification:

Hello! Sorry for the inconvenience - you have come across an issue that is currently being fixed internally but has not yet been fixed.

In the meantime, to work around this, please follow these steps:

  1. Quit Navigraph Hub from the task tray:

  2. Download the latest update from our website and install it

  3. The app should open automatically. If you still have a purple screen and/or error - please continue.

  4. Quit the app from the task tray again.

  5. Now uninstall the app. Step #4 is essential, skipping it will make your installation corrupt and cause the error in your previous screenshots.

  6. Check %localappdata%\Programs\navigraph-hub - this folder should now be empty. You should also be able to delete it, but you don’t have to.

  7. Install the app again. It should now work as expected!

Let me know how this works!

Kind Regards,
Malte

There is no hub in the task tray. The app doesn’t show up in the The settings->installed apps listing.

When I try to install the app, the install bar shows it completing but the app appears to attempt a second install - which is why I think that I get a second notification that the app needs to be closed. I believe that is also why I can’t delete the Navigraph Hub folder and get the notification that the NH can’t be deleted because it is being used:

First off, there is no Navigraph hub in the task tray. There is no Navigraph Hub in the installed apps list. I downloaded the latest update from your site - but it won’t install even with admin rights. Without the app showing in either area, it is impossible to uninstall it. As noted I can’t even delete the folder in %localappdata%\Programs\navigraph-hub

1]no app in the task tray
2]no app in the app listing
3]can't delete the folders
4] the install program appears to try a second install right after it appears to complete an install

confusing as hell.

Can’t complete items 1,3,4,5,6,7 in your email.

Ian:
Interesting addition to my problem: today I cannot log in to Navigraph.com . I can acces the site only by the support portal.

The message in your screenshot indicates that there is a Navigraph Hub process still running. You can end up in this scenario when uninstalling the app without quitting it, and we’re working on a fix for that.

I assume that you have tried restarting your computer? It is possible that this weird state persists across restarts, given that Navigraph Hub can be configured to start when your computer starts.

In order to make sure that Navigraph Hub is not running, please:

  1. Press Win + R
  2. Type cmd and press enter
  3. In the terminal prompt that appears, type the following:
taskkill /F /T /FI "WINDOWTITLE eq Navigraph Hub"
  1. Note the result of the command. Are there any new lines with the text “SUCCESS”? If there is, please try running the installer once again.

I am not entirely sure what is meant by this, but it is not possible to install two instances of this application on the same computer. One installation will overwrite the other!


Please do not attempt to use admin privileges at any point during the usage and/or installation of the Navigraph Hub. It is not needed.


If you continue to have issues, it might be worth looking into other ways of determining what process is locking your folder and preventing you (and the installer) from modifying/deleting it. There are tools that let you do this, and the Locksmith utility from Microsoft is one of them! Here is a link, let me know if you need further help with this!

Now I can’t access Navigraph.com except through the support portal.

That is peculiar indeed! Our website is hosted using a Content Delivery Network provided by Amazon AWS. They are not reporting any outages at the moment, and the website is reachable just fine for us.

Perhaps you could try using a different internet connection, such as your mobile phone? It is not unheard of that there are issues at the ISP level, and unfortunately such issues are out of our control.

i can access the site from my mobile phone. What should I do now?
KC

That means that it is likely that the issue you are having with regards to accessing navigraph.com from your computer is related to your own PC and/or local network connection - maybe even your ISP. There is not much we can do to help you there.

Try restarting your computer, ensuring that your antivirus is not interfering somehow and that the firewall (either on your PC or your network) allows traffic to our website.

Navigraph Hub should be downloadable from this link:

Download Navigraph Hub

I’m not sure what’s happening now. Navigraph.com is now working just fine. Navigraph Hub still looks like it’s trying to install twice. I am using the latest install exe from the Navigraph site and running the exe with admin rights.

I am happy to hear that you can reach the site again!

Per previous correspondence, please never run any Navigraph hub-related executable with admin rights.

Did you have a chance to follow the steps that I provided to you in my earlier post?

Tried the taskkill statement with the following result:

Did you have a chance to look at the other steps mentioned in the same post? With regards to determining what process is actually locking the folder, preventing it from being deleted.

Also - have you tried opening the folder (navigraph-hub, the one you tried to delete) and deleting all files contained within? In my experience, this has sometimes worked around the issue.

I did indeed look at the other steps and followed them without success yesterday (there is a 1.2.13 version in another folder, and I got a shortcut to the hub on my desktop, but the hub didn’t start up when I clicked on it). I now have sopies of windows tools and power toys. I shutdown the PC and re-started it but the hub didn’t start up. Just now I ran the hub installer with what appeared to be the same results. I happened to look at the task bar and the hub was there(!?!). I clicked on he hub icon and it started up normally, allwing me to update hub items. I have absolutely no idea what I may have done right. I have added the latest version if the log file for you to see if there is anything new on it that you might see.
I don’t think I tried to delete the files in the navigraph-hub folder - but in my desperation I might have tried that later in the day.
I even looked through the registry to see if there were only one or two mentions; after an hour of looking and finding many registry lines, I gave up.

Thanks for sticking with me. Regardless of how things got settled, the problem appears to have been solved. Without your suggestions I would have eventually given up on Navigraph, no matter how much I didn’t want to.

Best regards and have a great day,
Kevin Cusack

This is great news! Thank you for the update, it is much appreciated.

It is likely that you managed to delete the files. Whatever process was holding onto them was no longer a factor, and the installation worked out fine!

We are working on improvements to prevent this situation from happening to anyone in the future. Thank you for your patience with us through this issue!

Please don’t hesitate to reach out, should you have any further issues. Have a nice day!

Kind Regards,
Malte
