OFFLINE installer for the latest updates - Last Update September 2nd, 2025

[virtuali]

After collecting all evidence and reports from users, we can confirm most of the problems users had, were related to their local Cloudflare nodes still outdated, so they weren't getting the same files we had on our servers.

This would sometimes (not always) appear as the Live Updater trying to downloading the same files over and over, which is not a bug, is in fact an indication the Live Updater is working, because it knows your files are old, it tries to download the new ones, but it get served with the same version, so it tries again the next time, and again.

To fix this issue, we made a very simple OFFLINE Installer, available here (it's the same file in two separate places, so you only need one:

Download from Mediafire.com
https://www.mediafire.com/file/fqi00a0noyhcjgm/Addon_Manager.exe/file

Download from Box.com
https://app.box.com/s/qm8yng7m0tcfad9s7vxr19kn61mgabl9

This offline installer will make do until we'll be reasonably sure almost all Cloudflare nodes have been updated. You can recognize if YOUR node has, by simply noticing if the Live Update doesn't download anything if you run it after this offline installer. If this happens, it means your local Cloudflare node is now fully updated, so you don't need to use this anymore, just the Live Update.

IMPORTANT NOTE: The Airport Services and Jetways sceneries ZIP files are supposed to be always downloaded, this is normal. Those kind of files are thousands of very small files that compress very well, so we found it was faster to always redownload them as single ZIP files, then check thousands of individual files if they are in need of an update.

Unencrypted versions of FSDT airport files for FSDT sceneries bought on the MS Marketplace will also be downloaded every time, this is also normal.

This Offline installer will only update the complete GSX code. It doesn't contain updates to object models or textures or new operators. Those are only available through the normal online Installer/Updater.

The latest updates are always posted here:

http://www.fsdreamteam.com/couatl_liveupdate_notes.html

The same page will be opened by clicking the Release Notes" in the FSDT Installer.

Thank you for this file, Umberto.

The way of using confuses me a little bit: I execute the installer and I can see that it copies a lot of files in my FSDT-folder. After that I opened the FSDT installer link and the window opens there I can update and config GSX and the other FSDT-products. Pushing the update-button for GSX a lot of files were copied, but it happens so quick, I can't difference a lot.
Now I'm confused: is the node, where my files were downloaded from an outdate one, so I have older files back again? For security I executed the offline installer again.
I'm not sure if I ever will be able meeting a situation where nothing ill be downloaded after using the offline manager; maybe a half of a day later new files are at the the servers already.

This takes me to a next question: where can I see if my FSDT-products are actually and the latest ones? I can push the update buttons ten times a day and everytime files will be downloaded and installed.

That's why I wrote:

This means, until you see the Live Update not downloading anything, because your local node finally got the same files of the offline installer, running the offline installer should be always the last thing you do.

Ive tried this but it will download anyway everything again?

I understand the way of working of the offlineinstaller.

But as far as I know it is a static thing, containg files from today. If I run the liveinstaller let's say on Wednesday, it will problably overrides the files from today. How will I know then, if there a later (newer) files on the server than today or the node still doesn't contain the actual files yet?

And that's precisely why, in the above instructions, there's this line:

I think this information, added to to the previous "until you see the Live Update not downloading anything, because your local node finally got the same files of the offline installer, running the offline installer should be always the last thing you do" sentence, should clarify what you are supposed to do.

Thanks, this solved the issue which I've experienced since the day of release.

I too am wondering how we will know when/if to update from the Live Update tool and maybe I can help summarize what folks are asking here. Please though help and correct anything if I am missing the point someone is particularly after but:

At some point in time there should be updates that you publish which will make the static (Offline) installer files provided here on this thread obsolete / old, correct? We will want to make sure we have the latest version of the GSX application. What will be the plan for distributing those updates to us end users? Will you simply publish another offline installer with the updated files on this thread, or do you think that will happen at a time after replication completes to all the Cloudflare nodes?

If you think it will likely occur after the replication to all the Cloudflare nodes completes, then what would be the best way for users to know this? Will you announce that folks should return to using the 'FSDTLiveUpdate.exe' to get the latest files or is there some way that end users are able to inspect the version of their local files to the version of the most recently published files by the FSDT team to see that an update is required and to know for sure if that an update download completed successfully. I think this has been the challenge with the update tool's current design as the only way to know if you have outdated files that need to be updated is to let the update run and try to watch and see if files are downloaded or not. This is currently further challenged with the Cloudflare nodes not yet in sync causing some users to not receive required files (if I am correctly understanding matters at present).

Maybe a simple enhancement here is to add a product version ID to the tool that shows your local installed version VS the most recent and available for download version.

Also one additional question: When you do publish a new update to the GSX program, do we expect to have a similar issue with Cloudflare nodes being out of sync across the network? Why did we have this issue with the initial release and what should we expect for future incremental updates?

I executed the installer, but nothing changed. Unfortunately, I still keep getting the same (Couatl engine hasn't started ) error at all airports.

  these installers have done nothing new for GSX in fact now its not even appearing to be installed and my universal installer appears as such (see attached with all objects hidden.

GSX now works in MSFS only if I manually start coutal64_MSFS manually.  I don't believe that I should have to do that.

Then you should post your log, as explained in the other sticky thread named "Couatl engine hasn't started - How to report a problem "

i try this offline installer but my live update continue to download and then closes (it's like a crash).

Any advices?

i try this offline installer but my live update

Please re-read my previous posts: you are not supposed to run the Live Update. The offline installer should be the last thing you do.
