These are the available Windows versions:
Windows installers and apps are signed by SignPath.io, certificate by SignPath Foundation. (Starting with YACReader 9.16)
You can get YACReader for MacOSX using the official package(recommended) or brew cast. Brew cask support is supplied by the community and might not be up to date.
You can find the official docker image here.
1. Install homebrew (http://brew.sh/)
2. install brew cask (https://github.com/caskroom/homebrew-cask)
3. brew install yacreader --cask
Note: Installation requires the current version of brew cask so if already installed, if brew-cask-0.35.0 already installed or higher we are good to go, if not: brew upgrade brew-cask
YACReader is available through Flatpak, check it here.

Didn't find a suitable package for your platform? You can download the latest tarball or clone the source code respository and build YACReader for your own platform. Let us know if you need any help with the building process.
You can find the development builds in a separated repository. This is usually the version I use and they should be fairly safe to use but there is always a chance something is broken, but it is the fastest way to get the new features.
Releases are hosted by Github, if you are looking for a previous version you can get it from here.
YACReader for desktop and server is free and open source, and it is developed and maintained by a single developer. The best way to support all this work and keep YACReader alive is to donate.
All the hours of work, the domain, the server and the website cost money. So please, if you like YACReader, buy me a coffee! ;)
Developing YACReader costs time and effort, and it also costs money. This website, which also hosts the forum where users get support, costs money to maintain, and it gets more expensive as the disk usage on the server grows.
The macOS and Windows versions are signed, and I pay for that myself. On Windows, I need to buy and renew a certificate periodically, and it is not cheap.
There are also other costs, like buying devices to test the software or develop new features.
YACReader would not be possible without you. Thank you to everyone who has helped the project over the years: the donors and patrons, the people who translated the apps, made packages for their systems or sent code, and everyone who reported a bug, suggested a feature, answered a question in the forum or told a friend about YACReader.
THANK YOU!
A special thank you to Elia Gregorio Méndez and Felix Kauselmann.

Hi!
I am the developer of YACReader and my name is Luis Ángel San Martín Rodríguez (1980). I am a software engineer working at Richie from Gijón (Asturias, Spain).

Open YACReaderLibrary on your computer and open the server settings. They show the address, the port and a QR code. In the app, add a server: scan the QR code, or type the address and the port. Your computer and your device must be on the same network.
Check these causes one by one:
The apps need a running server to browse your library. Comics that you import to your device are available offline. To keep your library available all the time, run YACReaderLibraryServer on a NAS or a home server. It does not need a desktop, and there is an official Docker image.
Swipe from left to right on a comic or folder in your library. You can delete in the table and grid views.
Swipe with two fingers over the items to select them quickly. Watch this video to see how it works.
Touch and hold a comic or folder to open its context menu.
A library is a folder with comics. Usually you need only one library for all your collections. Click the + button, give the library a name and select its folder (for example C:\Comics). YACReaderLibrary imports all the comics and folders in it. Your files stay where they are.
Put the comics or folders in the folder of your library, then update the library. You can also set YACReaderLibrary to update your libraries automatically.
YACReaderLibrary cannot write its database. Make sure that you can write to the library folder. If your comics are in a network folder mounted with Samba (CIFS), mount it with the nobrl option (some documents call it nolock). Without it, the database cannot lock its files.
Each library keeps its data in a hidden .yacreaderlibrary folder inside the library folder. Move or copy the full library folder, then open it in YACReaderLibrary as an existing library. Your metadata and reading progress stay with it.
Update the drivers of your graphics card first. Then, in the settings, move the performance slider to the left and turn off VSync.
Write in the forum or open an issue on GitHub. Tell us the version of YACReader, your operating system and the steps to reproduce the problem. If a comic file causes the problem, tell us that too.
