I don’t understand why on this latest 6 May update and on the previous WU the Microsoft Store makes me download 171GB. Surely it should just be actual changes and not the entire game?
I never seem to be able to play MSFS anymore, I always dowloading - and it doesn’t help that download speeds are ridiculously slow sometimes.
When looking to install updates I believe the Store looks at your installation then downloads any file which does’t match what you already have. Therefore, as long as nothing has been changed or corrupted, it should only download what is needed.
When the Store says it wants to download 171GB (which incidentally is way bigger than the core files it’s updating, 125GB is nearer the mark) this is what’s available - but for me it never downloads it all, just what has changed. So does it actually do a full 171GB download (to me that would be a disaster of epic proportions as it would take all day and night!)?
IMO you may have a problem with your installation, 171GB is wrong. Does the game install to your C: drive or did you ask it to install elsewhere? If the latter do you ensure that the installation path is correct when it offers the download? Have you by any chance “moved” the game to a different drive? It may be worth having a good look at your disk drives to see if there are any “rogue” files anywhere.
Can’t offer any other ideas but, judging by reports on the forum, as the vast majority of users appear not to have the same problem I hate to say it but if it’s not one of the above you’re doing something wrong.
Thanks for advice. It is on C: on a SSD with more than enough space ( on a new Ryzen7 with nothing other than MSFS on it) and has never been moved. I do not have any third party addons either. I just can’t understand it. Its making it not worth having.
After the WU 4 last time of 171gb, I still had to go to the Marketplace and down another 20gb or do of updates. Crazy
It’s really difficult to determine if have done something “wrong” because I have only ever just followed the prompts from MSFS after it does the “checking for updates” when starting the game. If there are updates it automatically takes me to MS Store and the usually a 1GB installation file downs loads from MS Store before it then asks me to “Play” - this is the pointy at which it starts downloading 171GB - I have no other options available.
Hmmm, puzzling. One last possibility is that your SSD is failing. Maybe do a disc check on it - I think most SSDs have a self-checking/reporting feature.
Do you know any computer geeks? 
No, I see there are a number of new reports from other users with the same problem.
i am stuck on the d/l at 2.40 gb to go. Has anybody else have this problm, if so how did you fix it
I’m having the same problem. Installed 91gb from the discs and now it’s telling me that there is another 93gb to download. I hope not because my SSD doesn’t have that space on it.
Whoever is responsible for the installation package for this game needs a good square boot in the pants in my opinion. It’s a nightmare of epic proportions that can be seen all over the internet by the thousands of problems that have been encountered. User friendly it certainly is not! Also the Microsoft Store website is one of the most clunky ever built. I had to jump through hoops to get the installation to download to a drive with enough space on it before it even started downloading.
Lazy, incompetent programming at its worst.
It seems that I have the same problem.
After enjoying the sim the whole time with up and downs.
Now i have to reinstall the complete simulator after Update was published.
Did this fix your problem???I’m still stuck on 2.4 gb to d/l . PLEASE LET ME KNOW PLEASE PLEASE

THANKS
I’ve been forced to download the entire thing at least 10 times. I have no advice but know you are not the only one suffering with this.
I had a similar issue recently - forced me to redownload all 171GB which took around 12 hours… I logged a zendesk and received the following
The first time you set up the game you chose the installation path. This is the folder that the launcher is scanning to retrieve the content. If the launcher finds that this folder is empty or missing (does not exist anymore), it will try re-downloading the missing packages or the entire game if necessary. If you install additional packages outside of this folder, the launcher will not be able to retrieve the corresponding content.
To fix this issue, please update the UserCfg.opt file to point the launcher to the correct folder or move the packages into the correct folder.
By default, you’ll find the UserCfg.opt at the following location:
MICROSOFT STORE VERSION:
C:\Users\YourUsername\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache
STEAM VERSION:
C:\Users\YourUsername\AppData\Roaming\Microsoft Flight Simulator
Open the UserCFG.opt file with Notepad , scroll down to the bottom of the page, and update OR delete the “InstalledPackagesPath line.”
By default that line looks like this:
MICROSOFT STORE VERSION:
InstalledPackagesPath “C:\Users\YourUsername\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages”
STEAM VERSION:
InstalledPackagesPath “C:\Users\YourUsername\AppData\Roaming\Microsoft Flight Simulator\Packages”
NOTE
If you update the line yourself, simply copy-paste the correct installation path. For example:
InstalledPackagesPath “D:\Microsoft Flight Simulator”
If you delete the line, you’ll be asked to choose the installation path the next time you launch the game. Make sure to select the folder where your packages are already installed.
