Manual installation of the ASE (AirlineSim Enhancement Suite) chrome extension

The ASE extension is no longer available on the chrome store and the developer is no longer active. I know some people are interested in re-installing that extension, but can’t get it any longer.

If you are interested in installing it you can follow the steps below.

Please note:

This is not a supported installation. It’s a manual installation of the files outside of the chrome webstore install.

If you are not comfortable downloading files from the internet or following instructions from a forum, don’t do this. I generally recommend people don’t do this anyways, unless they really understand what they are downloading, installing, or doing to their computer.

That said, if you want do a manual installation of ASE 0.6.4 this is how you do it.

  1. Download the attached file and save it somewhere. Doesn’t matter where, but it should be somewhere permanent. I can’t upload zip files here, so I renamed it to a cvs. When you download it, rename it from a .csv file to a .zip file.

  2. Unzip it.

  3. Open your browser and go to the following URL:

Other browsers will have similar setups. I know in Edge, chrome://extensions redirects to edge://extensions and then same basic process continues.

If you can’t figure it out for your browser, let me know what browser you have and I’ll try to get you the information on how to do it.

  1. In the upper right corner is a slide bar that says “enable developer”. Enable it.

  2. In the upper left should be a button that says “Load unpacked”.

  3. Click that button and then find the folder that you unzipped ASE into. Find the folder “0.6.4_0” and then click “Select Folder” in the lower right.

That should add it to your extensions and enable it.

If you have any questions, feel free to ask them here.

0.6.4_0.csv (85.1 KB)


When I try to download it says the file is corrupted.

Did you rename it to a zip file? I can’t upload zip files here, so I changed the extention to .csv (which is allowed).

Download it, change the name to and you can unzip it using any compression program (winzip, 7zip, etc).

Does anyone has problems with this extention?
And does somebody know, if it will still work in 2024 when Manifest v2 will not be supported anymore?

I made an updated version of it in the other thread but none of the things that were broken before were fixed.

Making an updated version to V3 isnt hard and I have partial V3 version already done but it doesnt fix anything.

Any other Chromium based browser that isnt Chrome “should” work with V2 just fine.
