Install DeepCharts and activate the license

Installing DeepCharts takes five minutes when all goes well, and an evening when one of the three classic traps shows up: a Windows in French, a missing system component, or an installer launched from inside its archive. This lesson walks through the installation in the order that avoids all of them.

Before you start, check that there is free space left on the C: drive, even if you install elsewhere: the installer writes there anyway.

The installation, step by step

1. Get the license on my.deepcharts.com. The license key then appears in the client area.
2. Switch the Windows display language to English. It is counterintuitive, and it is the number one cause of failure: on a Windows in French, the installer stops on a Setup Failed message, often with code 0x80070643. Control Panel, Region and language, English as the display language, restart. You can switch back to French once the installation is done.
3. Update the Microsoft components: .NET Framework 4.8 or newer, and the Visual C++ Redistributable, in x86 and x64 versions. A missing or outdated package is the second cause of failure.
