Installing on a Mac
Open the downloaded .dmg file.
Drag Paidwhere into Applications.
Open Paidwhere from Applications and choose where your Paidwhere folder goes.
Installing on Windows
Open the downloaded setup file.
If Windows shows "Windows protected your PC", choose More info, then Run anyway. The Windows version does not carry a code-signing certificate yet, so Windows asks once.
If the PC lacks Microsoft Edge WebView2, the installer adds it, which needs an internet connection.
Open Paidwhere from the Start menu and choose where your Paidwhere folder goes.
