OFFLINE installer for the latest updates - Last Update November 21st 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reports from users, we can confirm most of the problems users had, were related to their local Cloudflare nodes still outdated, so they weren't getting the same files we had on our servers.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.

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.
