Microsoft Flight Simulator Fix for Stuck on Please Wait… 3.68GiB Remaining

This is what worked for me:

1. Close flightsim

2. Navigate to C:\Users\USERNAME\AppData\Local\Packages \Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Official\OneStore

3. Delete all fs-base-cgl-0.1.21.fspackage.NNN and fs-base-cgl-0.1.21.fspatch files.

4. Launch filesim. It will download all those files again and hopefully decompress them correctly this time.

5. Then it will continue downloading/decompressing more files.

This issue seems to be caused by flightsim crashing while decompressing fs-base-cgl. Unfortunately, this seems to be one of the biggest archives downloaded, weighing in at ~56GB. This archive is split into 2gb chunks and as the updater decompresses each chunk, it deletes it.

If the updater crashes after deleting the first chunk, it has no way of recovering and just gets stuck.

The short method above just wipes everything, but we should be able to save what is already downloaded:

1. Close flight sim.

2. Go into C:\Users\USERNAME\AppData\Local\Packages \Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Official\OneStore

3. You should find a bunch of fs-base-cgl-0.1.21.fspackage.NNN files (in my case numbered 003 to 031) and a bunch of fs-base-cgl-0.1.Y.fspatch files.

4. Note that some of the some of the fspackage.NNN files at the start are missing (the sequence should start from .001)

5. Move all the fspackage.NNN files to another folder somewhere else on your system,

6. Delete all the .fspatch files. (they only total about 30mb)

7. Relaunch flight sim. The content downloader will start download the fspackage.NNN files again.

8. Once it has download all the fspackage.NNN files you are missing, close flight sim.
   because mine crashed while extracting the 3rd file, I only had to redownload 4gb.

9. Copy/move all the fspackage.NNN files that you moved away earlier back into the Packages/Official/OneStore folder. They should total 56GB.

10. Finally, launch flightsim and let it continue updating. It should skip straight to downloading the .fspatch files and then decompressing fs-base-cgl-*

Hopefully this helps someone out there avoid a full redownload.

1. Some other versions of the game (like the steam version) might put the downloads somewhere else.
   If you re-launch flightsim, before the downloader starts updating, it shows you which folder it’s updating into (and allows you to select a new destination on a new folder or drive). Use that to work out where the files are stored.

2. If your folder has fs-base-cgl-0.1.21.fspackage.001, there is no need to do the long method above moving things around.
   If it’s just slow downloading, you will have to wait until all the .fspackage.NNN files are downloaded all the way upto .031.
   If it has all the fspackage from .001 to .031 and it’s just stuck on “Please Wait” you can probably just kick start it by deleting the .fspatch files.

3. You can probably adapt these instructions if it’s stuck on downloading something other than fs-base-cgl. I recommend trying to deleting the .fspatch files first.

4. If the updater says it’s decompressing fs-base-cgl, don’t stop it. It’s a large archive (56gb) and might take a while, especially on a spinning hard drive. You can watch it count up to fspackage.031
