How to Install Putty on Windows

This article provides detailed instructions for installing PuTTY on Windows 10, 8 or 7. However, the installation is similar to other Windows versions.

Download the installation package

First, you need to download the installation package (For instance,, putty - installer.msi ). If you have a 64-bit Windows computer, you should install the 64-bit version putty-64bit - installer.msi. Almost any computer purchased after 2015 has a 64-bit processor, except for low-cost processors. Many high-end computers sold a few years earlier also used 64-bit versions. If you don't know or don't care, it's safer to use 32bit version (putty - installer.msi).

You can download the installation package here.

Start installation

On Windows 10, Edge browser will run the installer when the download is complete. Just click to install the software.

On older Windows versions, you may need to run the installer manually. Open Windows Explorer (right-click the Windows icon in the bottom left corner), navigate to the Downloads folder (or wherever you saved the installer), and double-click the file name.

Note: However, the installation must be done with admin rights (or with an admin account or your personal account must have admin rights).

Sometimes, some people may have trouble installing MSI files.

Configure and install

When the installer starts, it will display the welcome screen. Just click Next .

The installer will then ask for the destination folder to install the software. Almost in all cases, a practical approach is to use the default value. Just click Next .

Then, the installer will ask for product features to be installed. You may want to add a shortcut on the screen if you want to use the software regularly. All other options should be enabled. When everything is ready, click Install .

When the installation process is completed successfully, the screen with the message ' Completed ' will display. Click Finish to exit the installer.

Run PuTTY

After a successful installation, you should check to make sure PuTTY is running properly and you can find the program. If you have a shortcut installed on the desktop, you will be able to find the PuTTY icon here. Try clicking (double) on this icon and the software will be opened.

If you don't create a shortcut on the desktop, you'll be able to find software from the Windows Start menu in the lower left corner of the screen. The Start menu will vary slightly in every Windows version. On Windows 10, scroll down until you see PuTTY. Open and select PuTTY .

When the software starts, you will get a window with PuTTY Configuration header with a Host Name field in the upper middle section. Try entering the server name to connect in that field and click Open.

How to have a server

SSH client helps connect to the SSH server. Since you installed PuTTY, you already have a server to connect to. Server can be placed at your own university, agency or home. You need the server name (For instance,, student.example.edu) or IP address (For instance,, 177.33.189.54) to connect. Enter the server name or IP address into the Host Name field.

If you don't have a server but want to use it, try installing Tectia SSH Server for Windows or IBM mainframes or OpenSSH on Linux.

Other SSH clients

PuTTY is a pretty good client, but it's a bit old. Its user interface is very outdated and it does not provide a graphical interface for transferring files. For alternatives, see the following SSH clients.

SSH client is a program that allows to establish a secure and authenticated SSH connection to SSH servers.
