Double click the PuTTY icon to start the PuTTY SSH client. If you created the PuTTY desktop shortcut during the installation, then you have the PuTTY icon on your desktop. The installer will inform you when the install is complete. If you are prompted to run the PuTTY Installer, then allow it to run. Change the Add shortcut to PuTTY on the Desktop from unavailable (red x) to Will be installed on local hard drive. It is convenient to have a shortcut on your desktop. The installer next asks you which PuTTY features to install. Otherwise, enter your preferred destination folder. Normally, it is fine to accept the default. The installer next asks for the destination folder. The installer starts, showing the Welcome to the PuTTY Setup Wizard screen.

Navigate to the Downloads directory (or wherever you saved the installer) and double-click on the installer file name. The Windows logo key + e shortcut works for Windows 10 and earlier versions. Open File Explorer (Windows 10) or Windows Explorer (Windows prior to 10).

If you are not sure which version to install, then select the 32-bit version.

The 64-bit version of PuTTY-64bit installer.msi will provide better performance if your PC processor and Windows edition are both 64-bit (typically true for relatively new Windows PC).

The 32-bit version of PuTTY installer.msi will run on all 32-bit and 64-bit versions of PC and Windows editions that PuTTY supports.

Look for the Package files, MSI (Window Installer) for the 32-bit or 64-bit versions of the latest PuTTY release to download. Open a web browser to visit the official PuTTY download site at Step 2

Note: The installation must be performed with Administrator rights (either using the Administrator account or your personal account must have Administrator permissions). PuTTY is a free implementation of SSH, SCP, and SFTP for Windows, macOS, and Linux platforms. For security reasons, PuTTY has replaced the previously provided SSH Secure Shell for Windows as the supported method of remote access.
