How to Fix Download Error 499 in Microsoft Flight Simulator

Microsoft Flight Simulator takes you on a virtual tour of planet earth. You can travel to any destination and explore the world in the comfort of your home. The game sets the standard for PC gaming.

Yet, despite the fun it offers, Flight Simulator poses an alarming issue. The game fails to download successfully, causing users to waste their time and internet data on multiple downloads. The issue is heartbreaking, considering the hefty size of the software.

You first download the Flight Simulator executable, which comprises a small fraction of the full size of the experience.

After running the initial installation, you then have to download the in-game content. So when you launch the game for the first time, the Content Manager greets you and requests you to download the recommended content, which is up to 100GB.

You can then imagine the frustration when the download keeps getting stuck, or worse, failing after considerable progress. The Debug $$ Something went wrong with the download, see 499″ error message then gets displayed. The problem has existed since the launch of Microsoft Flight Simulator in August 2020.

For some users, the error is only due to issues with the game server. They can wait for some hours, try downloading the game again, and succeed. But that is not always the case. You might need to apply more active measures.

You could close the app and close steam, reboot your computer, and try launching the software again. But that does not work most times.
