Download & Install

Download the latest version of Charter from the releases page.

Windows

Currently, the installer is recognized by some antivirus software as a trojan, Windows Defender sometimes says it's Trojan:Script/Wacatac.B!ml, as there is no way to fix it other than to pay M$ money. You have to deal with it by ignoring the issue or turning check for that file off in the software, however most antivirus scanners say that the file is clean.

Autoupdater needs to have writing permissions where you installed the program to update it, so you can change permissions for the program directory once it's installed, give it administrator privileges or install it in a directory that's not protected.
