I can confirm that you must not install the Sim with administrator rights. I did that and it ended up in infinite loops due to the lack of write permissions. Btw, I encountered the same problem yesterday. It eventually installed after 3 hours.
Yes, I confirm that to fix the looping file problem, I had to limit my Internet connection to a speed WELL BELOW the DATA BANDWIDTH USAGE LIMIT set into MSFS options.
How do you know that’s what caused your problem? Just because you did that is no guarantee that’s what caused your problem, unless you’ve tested a million scenarios and narrowed the issue down to that one problem. Without full debugging and running all kinds of scenarios, that’s like saying you’re having this problem because you brushed your teeth this morning.
I got around the looping problem by killing the game. Then it came back and wanted to install 35 GB, which it did in about 10 minutes and the game was off and running again.
Wouldn’t it be funny if the file permission problems the game seems to be having are what’s behind all of the performance issues people have been seeing, IOW, tied to the DRM the game/OS uses. Yeah, kind of a stretch in thinking, but…
It was part 2/4 that was looping 01.156.8.0 only 112 Mb but now it is wanting to download 34.89Gb and will not move past 4.58 Gb.
I have had constant CTD and Blue screens of Death yesterday.
Why cant we have an option to decline updates ?
Yep.
That way I said “at least for me”.
I’m only sharing my experience because I work with networks and you can see clearly that the Microsoft update Servers close the connection because of the download cap.
Look in Task Manager | Performance tab the Ethernet graphic when you are downloading the update, ideally it will be a straight line not a roller coaster.
You cannot decline updates. The server model they use requires everyone to be using the same software. Despite how it may feel to you, this is a distributed platform, it is no longer a piece of software that only sits on your own PC. At the current level of technology in the world, there is zero chance they could possibly manage all the versions that would be in the field, especially with all the updates they are producing. Every single line of code interacts with the whole package.
same problem, download a update (in past mostly at world updates) it stucks or loops, I pause it, restart MSFS and suddenly 87GB. Now with patch to 1.15.8.0 too. It sucks - really. So good the sim might be in game, the installation/update procedure is a whole mess
My problem is. That I felt the same way as most people here. However, what was added to the fact that it loaded 34 GB afterwards. For this he needed a day 19 hours…
Also an update in the store he loads very very slowly. I do not know what to do. The bandwidth is not limited.
yo tengo el mismo probé hace 5 días y aun no puedo dar solución, he intentado mil y una opciones y no da. a Microsoft y Asobo recomiendo evitar dar fechas de nuevas update y trabajar de una manera mas eficaz por que somos muchos los perjudicados. la update de reino unido corría perfectamente que carajos hicieron!.
The World Update 4 is 88 GB ???
What is going on?
It downloads 88 GB for real.
Update : I did not use any IPv6 and Bandwith was limited too for testing which did not help.
It ended now in again downloading 88 GB which resulted in the same Issue with last Update Patch
File FS-Base and after unpacking this 2 Rar Files it looped again downloading that pack and then crashing the Applikation.
After a restart it again downloaded 88 GB which then worked.
Then the World Update 4 could be installed.
So at the and around 185 GB Downloading for a usually Short Patch and a World Update 4.
I had zero Issues with my Installation before.
Not good.
@Hester40MT After you pointed out the unified language, marginal. What solution do you see to the problems raised here? Like my problem with a download that takes so long?
Isn’t that rather the problem. Than the language?
And by the way, you can translate the text yourself. I trust everyone here to do that. But of course it’s better to go into something like that than into the problems that exist…
Nice that everyone has his task 
and there is always a nice text where you protect one Nice that everyone has his task
And no thanks for the tip I will try it
Ok, pls check the following file in the path: “C:\Users\User\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache”
UserCfg.opt
The last line in the opt file should contain the path to your msfs folder which in my case is:
InstalledPackagesPath “J:\MSFSPackages”
When I changed to 1.14.5.0 the path was suddenly changed to my windows drive C:\ for no reason. When You are at the point in the update menue where you see that path, it’s always positioned to the path where the update will install but might not be the path in the opt file. In this case change the opt file, save it and restart your sim again. No garanty but worth checking it.
I have managed the update. But with an eternity…
The problem that the download takes forever is still there. I tested it on an update from an airport from the content manager. It loads only with 2 to 3 Mbit. If I load normally via the browser I get a speed of 50 Mbit only in msfs not there it remains at the slow speed.
I have tried these tips without success.

Maybe someone has another idea?
Thanks a lot
Lol.. Jan 2026… other windows… this keep getting into a loop where download say up to 8 and then keeps trying to download 8/534 over and over and over. Ok NEW windows.. and got up to 11/534 and stops at some point 0.00 and then goes back and keeps trying to download over and over and over. REALLY? Its not on my end. When this frist came out.. and then many times after that I reinstalled it and worked fine. Now its stuck? This is odd no?
So tried 2024.. what are the odds it works flawlessly.. yet 2020 won’t. Odd huh hmm
Ok found this lol. What I tried this time was setting the download speed to 20mp out of 1g+…yeah I used Netlimiter and is now at 517. Been doing this since my first Atari 32.. ooh 32 bit color! So you know what to make sure its not at your end. MS knows whats going on.. MODS might not. So try if you have this problem set the speed to 20mb. I did try higher but keep looping.
