How do I install x737-800 - complete.zip (2.5 GB) and liveries in X-Plane 11 (Steam)?

Installing the x737-800 “complete.zip” + liveries in X-Plane 11 (Steam)

Hi Oleg — Steam vs non‑Steam doesn’t really change aircraft/livery install. What matters is you put things in the correct X‑Plane folder structure.

Part 1: Install the aircraft (x737-800)
1) Download location / find your X‑Plane folder
In Steam, the default is usually something like:
...\Steam\steamapps\common\X-Plane 11\
The important subfolder inside there is:
X-Plane 11\Aircraft\

2) Unzip the aircraft
Extract x737-800 - complete.zip with 7‑Zip/WinRAR (2.5 GB is big, so let it finish fully).

3) Place the aircraft folder in Aircraft
After extracting, you should end up with a folder that contains the aircraft’s .acf file (that’s the key sign you’re in the right place).

Put that whole aircraft folder here:
X-Plane 11\Aircraft\x737-800\
(or similar — name doesn’t matter, structure does)

Tip: I recommend not putting it under “Laminar Research” or “Extra Aircraft” unless the package author specifically says to. A dedicated folder under Aircraft keeps things tidy and avoids update/overwrite issues.

4) Start X‑Plane and load it
Run X‑Plane → choose a new aircraft → look for the x737‑800 in the list. Load it once, let it initialize.

Part 2: Install liveries
1) Find the aircraft’s liveries folder. It should be here:
X-Plane 11\Aircraft\x737-800\liveries\

2) Each livery should be its own folder inside liveries, for example:
X-Plane 11\Aircraft\x737-800\liveries\My Livery Name\

3) Inside each livery folder you’ll typically see objects/textures (often a file called livery.png and/or an objects folder, depending on how that aircraft does liveries). Don’t rename the internal folders unless the livery readme tells you to.

4) Load the aircraft in X‑Plane, then use the aircraft’s livery selector (usually from the Flight Configuration screen when you pick the aircraft) to choose the new paint.

Common problems to watch for

• Aircraft doesn’t show up: usually the folder is one level too deep (example: ...\x737-800\x737-800\something.acf). Make sure the .acf is directly inside the aircraft folder you placed in Aircraft.
• Livery doesn’t show: usually the livery folder structure is wrong (extra nested folder) or it’s for a different 737 variant.
• Zip extraction fails / missing files: re-download and extract again (big zips do corrupt sometimes), and make sure you have enough free disk space.

Quick questions so I can tailor this to your exact package
1) When you extract it, what is the exact folder name that contains the .acf file?
2) Do you see a liveries folder inside the aircraft folder after install?
3) What OS are you on (Windows/macOS/Linux), and does X‑Plane show any error message when loading the aircraft? If yes, paste the relevant lines from:
X-Plane 11\Log.txt
