Download infinite loop

Yep, same problem. Tried every suggestion for days now and endless attempts to download the 17GB file and it just loops at the end. Extremely frustrating. I am at my wits end with this. Actually requested a refund twice now on Steam and was denied. I’m going to escalate this debacle to Fair Trading complaints here in Australia. Microsoft, this is a disgrace!

je ni arrive tjrs pas a installer, l’installation se bloque tjrs sur fs-base-0.1.196.fspatch002

j ai trop envie de reprendre les commende mais malheureusement je ne pas

Despite the MS post (cf: “[SOLVED] Download loops”) saying this is now fixed, it isn’t - for me at least. I’ve tried all the user-posted fixes, e.g
netsh int tcp set global autotuninglevel
remove plugins
run netlimiter

What can be so hard about writing a utility to download zipped remote content, validate it, then decompress and install it? How can it be acceptable not to fix a broken version of it in a commercial product for weeks on end, thereby entirely bricking users’ installs?

It amazes me that such an incredible piece of technology as MSFS is, is currently unusable for want of a working file downloader util. Please Asobo can you address this again?? Your fix doesn’t work in all circumstances.



Mine got corrected with the MS server fix ( not sure what it was but the looping stopped for me) and the last patch solved my CTD issues for the most part. Like you, I tried everything posted to the community and didn’t have any luck. May be drastic, but have you entertained an uninstall and reinstall? Maybe Russian roulette but it could help…

Good luck in your endeavors!

Version is installed but i can’t get v1.19.9.0 and the Sim doesn’t even start anymore.
After trying to start the Sim today nothing happened. So i figured, there might be an update available in the store.
This update then was stuck in loop. After trying the Xbox App, multiple restarts, logout from the Store … it said, the update was installed and the Sim is ready to go. But still nothing happens.
While trying to solve the update loop, i also changed the timezone and sync settings, i also made sure i have every windows update and i also removed the Commuity folder from the install path.

Still, no update, not even shown, neither in the Store, nor in the Xbox App and the Sim is just dead.

edit: I did also the Store repair and now also the MSFS repair in the Advanced Options (Add/Remove Apps). Still nothing.
edit 2: uninstalled Xbox App, Restart, Reinstall XBox App → next try → nothing → restart → next update try, still nothing.

Since WU6 and the bs with the Xbox App, the Updates on the Sim are a nightmare.
Absolutely annoying.


Same issue. Can’t play the game now because of the download loop. I hope MS comes out with a hot fix on this issue quick!!

If everyone starts bombarding them with refund requests on Steam etc. they’ll soon acknowledge the problem. I’ll have to do it through Fair Trading complaint because the game has been installed for more than 12 months. It’s the principle though. No other game I own has this issue or complaints ignored for this long now.

after formating hard drive and fresh install of windows, 5 days of re downloading I managed to finish the instalation at last. Seems to be working… until the next update?


Same problem for me since the release of SU6 until today.

My update was looping on one of the fs-base-cgl patch files (0.1.74), this at 98% through the update. Pause, exit and restart resulted in the entire fs-base-cgl folder structure in the sim being deleted, requiring a new 60GB download.

I make system images of all my drives so restored the entire sim to try again multiple times, also trying most of the official and unofficial potential fixes which have been posted, none of which worked. I even tried connecting through a different ISP (tethered to my phones hotspot), no difference. The same patch file went into an endless download loop every time…

In the end I manually deleted the fs-base-cgl folder myself to let the updater download the whole thing - finally this worked as of this morning.

This is now the 2nd time this has happened to me since I first installed in June. The July update also failed with a similar issue and in the end I reinstalled the whole sim.

I think there are numerous causes of these update problems, some in the network infrastructure and some on the MS servers. The fact that the same file can fail to download repeatedly when others both large and small download fine without corruption does point to something wrong where the files are held or with some of the files themselves. I also question the update and fallback logic in the installer and the lack of any diagnostic tools to pinpoint what might actually be going wrong in detail e.g. a switchable trace log.

I am thoroughly fed up with this whole process now - I’m on a limited speed connection (20mbs) so downloading repeatedly takes a great deal of time and I have a broken product I can’t use all the while. In all the years I have used and programmed PCs and played online games and flight simulators I have never had this much trouble with updating.


Being absolutely annoyed and having tried everything i found (posted in my previous reply), i contacted the Support to try to get help. I told them, what i have already done (copied my posting, wasn’t willing to write that all again) and got a pretty fast reply.
Who would have guessed … it was the same steps you can already find on the internet and i did try even more then that. So very helpful advice in the first place
Just to be save, i took the time (about half an hour) to redo those steps in the exact order they provided me just to be at the same situation like before.
MSFS2020 doesn’t start, the store says and if you try to start MSFS2020 from the stupid Xbox App it just opens the Store with the Gaming Services which are already installed.
This is a f***ing joke to me.

Same problem here. Download start looping at some point and game stays unplayable until the download system is fixed.

same problem here also.

Im dealing with this issue as well… so yesterday i completely uninstalled the game and attempted to do a fresh install. The same issue is occuring with the new install.

The Installation Manager shows that a package is downloading, but no progress is actually made


and the .part file is showing 0 bytes.

I get to 46.7 gigs then crash to desktop, then it crashes when trying to resume.

Same issue. Game is broken. What a joke. Getting a refund

Bonjour a tous , j’ai également eu le même problème depuis la mise a jour world update 6 et quand j’essaye d’installer FS2020 je reste dans une boucle infini
exemple : au début du téléchargement sa décompresse “fs-base-0.1.165.fspatch” et lorsque je suis au dernier fichier “fs-base-0.1.198.fspatch” sa me remet sur le tout premier . Donc je suis plongé dans une boucle INFINIE . Après avoir chercher des information et des vidéos YTB sur se problème j’ai enfin réussi a passer cette étape de boucle infini et mon téléchargement a repris normalement .
Voici les étapes:

1.installer : NetLimiter 4 et regardé cette vidéo : [CORRECTIF FACILE] Microsoft Flight Simulator | Dépannage d’installation

  1. si malgré les valeurs qu’il a mis sa refait le même problème mettez : 300 KB/s
    perso pour moi sa ne fonctionnait pas avec 427.25 KB/s donc j’ai mis 300.
    ( le téléchargement sera plus long mais au moins sa téléchargera votre jeu.)

  2. essayé de désactiver les anti-virus comme : Avast
    (personnellement Avast bloquait les téléchargements et les décompression de certains fichier )

Personnellement toute ces astuce m’ont aidé a télécharger FS2020 donc essayé les.
et n’oubliez pas de réactiver les anti-virus et remettre votre bande passante en illimité lorsque FS2020 sera téléchargé.
Bonne journée et j’espère fort que vous aller réussir a téléchargé FS2020.


Thanks for sharing this or should I say Merci Beaucoup :smiley:

moi ton conseil na pas marcher pour moi mais merci quand même

Thanks so much for this post.

I had tried everything else - but disabling my (AVG) antivirus finally fixed the problem.

I didn’t have to throttle my connection with Netlimiter or anything else once I’d done this - it just all worked.

seems to have several people citing this as having fixed their issues too.

Make sure to disable any antivirus software during the update.

For me I had this issue since Avast was silently blocking msfs access to one of the “LOADING” folders inside the steam lib.
