Can't download Microsoft flight sim 2020

Alright, I appear to have finally figured out what was causing the downloads to keep looping to 0%.  I came across this troubleshooting page:

https://flightsimulator.zendesk.com/hc/en-us/articles/360016844080-Download-stuck-on-packages-Install-loop-Decompressing-issues

The specific step that fixed the problem for me was "Disable Window Auto-Tuning"

A) Disable Window Auto-tuning

• In the Windows search bar, type Command and look for ‘Command Prompt’
• In the menu select “Run as administrator”
• Enter: netsh int tcp set global autotuninglevel=disabled
• Press enter
• Reboot your computer

Apparently Window Auto-Tuning can have issues with old networking gear.  I use my neighbor's internet, and it is an old and crappy Arris router which is likely the culprit.  I've been downloading steadily with zero loops since I changed it.  Hope this helps, for what it's worth.

No suggestions, thousands of us in the same boat.  I have tried new WIn10 installs, new internet service providers, all the tricks and hacks mentioned in this ridiculously long threat and NOTHING fixed it.  Its a joke, nothing else to describe it.

I have are 2 devices that device manager recognizes (as PCI Device and SM Bus Controller) but can't find drivers?

Sorry I not able to resolve the MSFS2020 problem but I may be able to help you find your missing drivers...

1. Go to the Device Manager by right click on Windows Start.
2. Double click on the missing PCI Device or SM Bus Controller device.
3. Then click on the Details tab, in the Property menu select Hardware IDs.
4. Copy the Hardware ID value but there might be more than one, so copy all.
5. Now google searches each Hardware value and you should find the drivers.

P.S. The driver file will have *.INF extension and click Update Driver to manually install on your device.

Hope you find this helpful and good luck!

I installed MSFS 2020 (Deluxe) from the store, but when I click play, nothing happens. Ideas?

Thanks  Jim Tanis

Try running the game as an administrator, right-click on it either on the desktop or in the Start menu and then select Run as administrator.

Or try to launch MSFS2020 by using the Xbox app and also check your firewall on Windows system or modem is not blocking the game.

I am the same as Gary. Fix does not work for me. 

I have wasted many hours trying to fix this.
