# Install DocInsight

Install DocInsight before you create or build documentation projects.

## Before you start

- Use Windows 10 or Windows 11 on x64 or ARM64.

- The Delphi IDE extension requires Delphi XE7 or later. Close any running Delphi IDE instances before installing the extension.

- Microsoft HTML Help Workshop is required only if you build CHM output.

## Run the installer

Download the current DocInsight Insiders installer from the official Download page, then run it.

During installation, you can select:

- Add DocInsight to PATH (User Environment) to run `docinsight` from a terminal.

- Delphi Extensions to install the extension for selected Delphi versions.

- Microsoft HTML Help Workshop (CHM Compiler) to build CHM output.

DocInsight installs for the current Windows user and does not require administrator privileges.

## Verify the installation

### Verify the CLI

Open a new terminal so that it picks up the updated `PATH`, then run:

shell

    docinsight --version

### Verify the Delphi IDE extension

Open a supported Delphi version and check that the splash screen shows the DocInsight product version. After the IDE starts, check that the top-level DocInsight menu is available.

For supported Delphi versions and IDE architectures, see Delphi extension compatibility.

## Silent installation

Use `/silent` to hide the normal setup wizard while keeping the installation progress window visible.

Use `/verysilent` to hide both the wizard and the progress window.

For a fully unattended installation, also consider `/suppressmsgboxes` to suppress most message boxes and `/norestart` to prevent an automatic restart.

For more options, see the Inno Setup command-line documentation.

## Next steps

- Activate DocInsight with a license, or continue in trial mode.

- Follow the Quick start to create and build a documentation project.
