## More information

#### Windows

Extract the downloaded archive somewhere on your hard disk:

- Extract to a directory where you have read and write access.
- There is no need to extract to an empty folder, as all files in the archive are contained within a root folder.
- Don't extract in too deep a path as then you may get issues with too long paths.

Execute `eclipse-escet.exe` from the directory that contains the extracted files to launch the Eclipse ESCET IDE. The `bin` directory contains the command line scripts.

For more information on the Eclipse ESCET IDE, see the Eclipse ESCET general toolkit documentation. In particular the section on starting the Eclipse ESCET IDE for the first time.

#### Linux

Extract the downloaded archive somewhere on your hard disk:

- Extract to a directory where you have read and write access.
- There is no need to extract to an empty folder, as all files in the archive are contained within a root folder.

Execute `eclipse-escet` from the directory that contains the extracted files to launch the Eclipse ESCET IDE. The `bin` directory contains the command line scripts.

For more information on the Eclipse ESCET IDE, see the Eclipse ESCET general toolkit documentation. In particular the section on starting the Eclipse ESCET IDE for the first time.

#### macOS

Make sure to download the Eclipse ESCET version matching the architecture of your Apple computer. The x64 version will work on older as well as newer Apple computers. The aarch64 version natively supports newer Apple computers with an Apple M-chip, and therefore runs faster than the x64 version on those computers. The aarch64 version does not work on older Apple computers with an Intel processor. To find out what architecture your Apple computer has, check out this Apple Support page.

Add the Eclipse ESCET app to the Applications folder:

- Open the downloaded `.dmg` file by double clicking it. This opens a window with the Eclipse ESCET app and a shortcut icon to your Applications folder.
- Drag the Eclipse ESCET icon onto the Applications folder icon. This causes the Eclipse ESCET app to be copied to the Applications folder, where all apps can be found.
- You can now open the Eclipse ESCET app from the Applications folder.

The first time you open the Eclipse ESCET app:

- Dismiss the popup with error message "EclipseESCET" can't be opened because Apple cannot check it for malicious software or "EclipseESCET" can't be opened because it was not downloaded from the App store by clicking OK.
- Go to the Apple menu, select System Settings..., click Privacy & Security in the sidebar, and then scroll down to the Security section on the right.
- Under Allow apps downloaded from, click the Open Anyway button just after "EclipseESCET.app" was blocked from use because it is not from an identified developer, to allow the Eclipse ESCET app to be executed.
- Approve the application with your credentials in the next popup.
- Start Eclipse ESCET again (if not restarted automatically), and when the popup appears with the same error message as before, click Open.

For more information on the Eclipse ESCET IDE, see the Eclipse ESCET general toolkit documentation. In particular the section on starting the Eclipse ESCET IDE for the first time.

#### Eclipse ESCET command line tools

After extracting the downloaded archive, the command line tools are located in the `bin` directory. The command line tools are only available for Windows and Linux, not for macOS. You may want to add the `bin` directory to your `PATH` environment variable. See e.g. How do I set or change the PATH system variable? for how to achieve this.

To see which tools are available, simply look in the `bin` directory. Each of these tools can be started with the `-h` or `--help` option to get further information.
