Frequently Asked Questions

How to install add-ons

  1. Download the add-on archive file from one of the links we provide on each post. For a few add-ons, there are multiple archive files due to filehoster size limitations. In that case, you need to download all archive parts (XYZ.part1.rar, XYZ.part2.rar, …)
  2. Find your Microsoft Flight Simulator 2020 Community folder. This guide will help you find it.
  3. Extract the archive contents to your Community folder, preferably with the latest WinRAR version (you can get it here). If you’re using any anti-virus software, we recommend temporarily disabling it while doing so, it could block add-on files from getting extracted.
  4. Most add-ons can be directly extracted to the Community folder, with a few exceptions. Always check for Readme/Info text files within the files. After extracting, the path to the crucial add-on manifest.json file must look like this: Community\<addon_folder_name>\manifest.json

Current add-on warnings

There are some caveats about certain add-ons, we will keep this list updated. See the warnings in bold on each post:

Current add-on conflicts

The following add-ons are conflicting with each other, only one should be used. See the warnings in bold on each post:

Fixing MSFS crashes caused by add-ons

At one point, after installing lots of add-ons you might find the game to sporadically crash to desktop (CTD). This is most likely caused by several add-ons using the same name for ModelLib files and MaterialLibs folders.

To fix it, use MSFS Addons Linker by following our step-by-step guide.

If this didn’t help and CTDs are still occurring, try clearing your MSFS Rolling Cache as described here.

As a last resort if CTDs are still occurring, try deleting the Content.xml file which can be found here:

  • Steam version: C:\Users\USERNAME\AppData\Roaming\Microsoft Flight Simulator\Content.xml
  • Microsoft Store version: C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Content.xml

Fixing MSFS aircraft bugs & crashes

In case you are experiencing bugs, weird behaviour or even crashes when using a certain aircraft, try deleting all folders within the MSFS packages directory (used by aircraft for cache files). It can be found here:

  • Steam version: C:\Users\USERNAME\AppData\Roaming\Microsoft Flight Simulator\Packages
  • Microsoft Store version: C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\Packages

Note: Afterwards, in case you are using aircraft from SimPlaza that required running ACTIVATE.bat scripts, you need to run each script again.

Fixing ModsFire.com problems

If you are experiencing slow downloads from ModsFire.com, we cannot do anything against it other than recommending to wait a few hours and trying again.

If you are unable to access ModsFire.com links, try the following:

  • Use a different browser
  • Change your DNS settings (your provider might have blocked it)
  • Temporarily disable your Anti-virus software (it might block access to the site)
  • Use a VPN

If Cloudflare is blocking you temporarily from accessing ModsFire.com, this will most likely pass after a couple hours. These are just temporary bans.

Fixing AnonFiles.com problems

Some mirrored files of SimPlaza are hosted on AnonFiles. If you are experiencing slow downloads, try the following:

Sharing add-ons

If you own a MSFS add-on that is not yet listed on SimPlaza, we would love to post it. All contributions are very welcome!

We recommend zipping the add-on folder and uploading the archive to DropMeFiles, MEGA, MediaFire or any other filehoster of choice. You can then send us the download link by E-mail or on our Discord Server.

Please note that we can only post add-ons that were purchased from third party stores like simMarket. Add-ons purchased from the MSFS in-game marketplace are most likely DRM protected and thus useless. To check if an add-on is protected, search for files with suffix .fsarchive inside the add-on folder.
