Somewhere in those various instructions it may have instructed you to turn off your third party firewall. After a month of frustration, I almost accidentally discovered that turning off my firewall was not enough. I removed it entirely and activated the Windows 10 firewall. The program downloaded after that.
Just something else to try if you have a third-party firewall.
It seems most of the error troubleshooting on this code appear to be hardware related. Some are relatively straight-forward (i.e., tried install to external drive not fast enough for r/w process, incorrect/corrupt drivers) all the way to esoteric (two year thread where someone discovered a particular brand of secondary drive controller was not playing well with Windows).
Are you trying to install it to an internal or external drive, just out of curiosity?
Thanks for the suggestion, these are all internal SSD drives.
The error code in fact stands for “A device that does not exist was specified” and therefore I did run file system checks on all my drives (result: all is fine).
Also, installing other games apart from FS works fine, which pretty much rules out bad drives I would say.
There must be something specific to FS, maybe some setting left over pointing to a now invalid location.
I even tried tracing the Windows Store installation with Process Monitor, that is how desperate I have become.
Sounds like worth a try, but I see no way to run the XBox App or the App Store as Administrator: Right click and “Run as Admin” is not available, and the .exe files are somehow protected in the folder “C:\Program Files\WindowsApps” (I can see them as Admin, but not run them).
MS-Installer takes over after launching from the Steam Client (or shortcut).
Key Differentials:
I avoid the complicated Update/Interaction between MS-Store, XBox App, as well as login state etc.
I can install both the base Game Files (~1.6GB) and Official Packages (~110 GB) in custom folder paths, as long as those paths are inside Steam Library Paths (defined in the Steam Client).
I can get to all those files (Base plus Packages) freely without additional authentication and remove, update, change attributes etc.
Caveat: There is NO integrity checking function with the Steam version. Steam’s “Verify Files” would normally do what the MS-Store’s Repair - do a data and file integrity check, and re-install/update broken/missing files. Steam instead blows away the entire installation and hands it back to the MS-Installer. That’s because the MS-Installer in both versions is the paramount method to install and configre the sim. Many Steam users in the early days (and some still to this day) discover this the hard way.
Thanks @TenPatrol , “Online All” is my SAN policy.
I can not run MSFS as admin because it is not installed: I de-installed MSFS and now the Windows Store (or the XBox App) will not install it again, that is the problem.
I can install other apps and games from the Store or XBox, just not MSFS (installation fails, “Code: 0x800701B1”).
Thanks, but I already did all the usual suggestions one can find on Google, including updating and reinstalling everything (expect reinstalling Windows).
I’ve started to receive the 0x800701b1 error as well. I’m finding that if attempt to run the application from the menu bar without admin permissions, I receive the error message. If I run it from either MS Store or XBox app, I don’t have the admin option and I get the error message. What’s bugging me right now is I purchased the Premium Deluxe edition. The store and the XBox app show I own this version, but when I launch from the menu bar with admin permissions, I only have the standard aircraft, plus the two I’ve purchased. Go to Content Manager, I see the extra airplanes are installed and up-to-date, but I can’t access them. Strange. I didn’t have these issues until a Windows update yesterday. I’m going to try reverting Windows back when I have a chance, and see if that resolves any of this on my machine.
“I was finally able to work around it on Sunday by turning off my wifi during the initial xbox game services UI splash screen and then enabling it once the actual game launched. However, I’d really like to have it fully fixed and not have to do these extra steps. (This also worked for the Forza users above)”
it seems that this is exactly the issues that i am facing now. Deinstalled MSFS and tried to reinstall it to a fresh SSD gives me exactly the same error code. Most of the things i found on the internet did not work.
