Installing tak
Takes about a minute. You need Windows 10 (version 1809 or newer) or Windows 11, and no admin rights. A macOS version is coming soon.
Install
Download Install tak.exe
The link is in your purchase email. The file is about 40 MB.
Open it
If Windows shows a blue box saying it protected your PC, click More info, then Run anyway. It appears for new apps that don't yet have a download history with Microsoft.
Click Install
"Start with Windows" is on by default, so tak is there every time you sign in. A desktop shortcut is optional.
Click Open tak
A small chessboard icon appears by the clock. If you don't see it, click the ^ arrow next to the clock and drag the icon onto the taskbar so it stays visible.
