--- Comment #2 from badflagello badflagello@hotmail.it --- As May 2019 https://line.me/en-US/download is the official way to install it, however it seems that for Windows the only option to install is through the windows store (at the least that's what I see).
When I installed it many months ago you could simply download the normal .exe, and kept it up-to-date thanks to the in-app updates, so I don't know if the version from Windows store changes wine's behavior or not.
It seems that https://line.en.softonic.com/ has the regular .exe bypassing the store
1 click free download for windows green button 2 Click "continue to download" green button under "Alternative LINE download from external server (availability not guaranteed)" 3 .exe should popup.
Note that the version you will get is 5.16.2.1932
Which is what I assume I am running, as I aforementioned I think LINE updated has well before WINE launched the normal app.
If I find a way to confirm I am running 5.16.2.1932 I will let you know.
