In general to develop in C/C++ with CLion you need:
- CMake at least version 2.8.11 (if you do not want to use the bundled version), make
- GCC/G++ or Clang, which in case of Windows means using toolchains: MinGW 3.* or MinGW-w64 3.*-5.* or Cygwin 1.7.32 (minimum required) up to 2.8.*.
- If you are going to use Microsoft Visual C++ compiler instead of GCC/G++ or Clang, then Visual Studio 2013, 2015 or 2017 shall be installed. For more details, refer to our tutorial.

Note that Next button is still available; however, you might have problems while creating or opening without properly a configured toolchain. You can configure toolchain anytime later.
Disable the unnecessary plugins
CLion is shipped with a variety of plugins that provide integration with different version control systems and application servers, add support for various frameworks and development technologies, etc.
On the next step you can disable the plugins you do not need to increase CLion performance. If necessary, you can re-enable them later in the Settings dialog ( Ctrl+Alt+S under Plugins).
You can click the Disable All link for each group of plugins to disable them all, or Customize to disable individual plugins.

Manage CLion through Toolbox App
Toolbox App is a control panel that allows you to manage all JetBrains developer tools, including CLion, as well as your projects, from a single point of access. It lets you maintain different versions of the same tool, install updates and roll them back if needed. It also remembers your JetBrains Account and uses it to automatically log you in when you install and register new tools.
- Download Toolbox App.
- Launch the setup file.
Now you can manage existing tools, install new tools and download updates:
Perform silent installation on Windows
Silent installation is performed without any user interface. It can be used by network administrators to install CLion on a number of machines and avoid interrupting other users.
To perform silent install, run the installer with the following switches:
/S: Enable silent install
/D: Specify the path to the installation directory
/CONFIG: Specify the path to the silent configuration file
CLion.exe /S /CONFIG=d:\temp\silent.config /D=d:\IDE\CLion
Silent configuration file
You can download the silent configuration file for CLion at https://download.jetbrains.com/cpp/silent.config
The silent configuration file defines options for installing CLion. With default options, silent installation is performed only for the current user (
mode=user). If you want to install CLion for all users, open the silent configuration file with a text editor, change the value of the installation mode option (
mode=admin) and run the installer as an administrator.
