Installing SuperPutty is very simple, as it comes with an installer. It is packaged as a ZIP file, so users have to just unzip the downloaded application to where you want to store it on the local disk. Although, it is advised that the program is unzipped to a directory that retains the version number of the application as it follows a semantic version numbering system.
First you need to obtain a copy of the installation package (e.g., putty--installer.msi). If you have a 64-bit computer, it is recommended that you install the 64-bit version putty-64bit--installer.msi. Almost any computer bought after 2015 has a 64-bit processor, except for the very cheapest ones. Many high-end computers sold several years before that. If you don't know or don't care, it is always safe to use the 32-bit version (putty--installer.msi).
On older versions of Windows, you may need to run the installer manually. Open the Windows Explorer (right-click on the Windows logo in the bottom left corner), navigate to the Downloads directory (or wherever you saved the installer), and double-click on the file name. A detailed description can be found here. Note, however, that the installation has to be performed with Administrator rights (either using the Administrator account or your personal account must have Administrator permissions).
Then, the installer asks to select product features to install. You probably want to add a shortcut on the desktop if you expect to use the software frequently. All the other options generally should be enabled. When ready, click Install.
Choose the appropriate MSI installer version for your system. Download the 64-bit version for 64-bit systems or the 32-bit version of PuTTY if your system is 32-bit. Save the file to the desired folder.
5. Upon completing the installation, the program shows a 'Setup complete' screen. Check/uncheck the View README file option if you want to see the developer's notes. Click Finish to exit the installer.
Both PuTTY and PuTTYgen are required to convert OpenSSH keys and to connect to the server over SSH. These two tools can be downloaded individually or, preferably, as a Windows installer from the PuTTY Download Page.
Once the PuTTY Windows installer is downloaded, double-click the executable in the Download folder and follow the installation wizard. The default settings are suitable for most installations. Both PuTTY and PuTTYgen should now be accessible from the Windows Programs list.
PuTTY is an open source terminal emulator program which supports Kerberized ssh (as well as telnet). The PuTTY package also includes the command line programs plink, pscp, and psftp. These are similar to the Linux ssh (when used to execute a command a remote system), scp , and sftp commands. The latest PuTTY news can be found on the PuTTY Home Page. Get PuTTY by downloading the Windows installer for everything from the Fermilab Authentication Group's Kerberos for Windows page (or from the Putty Download page) and running the installer. If you plan on using the command line utilities plink and pscp, add the installed location of PuTTY (default is C:\Program Files (x86)\PuTTY on 64-bit systems) to the system-wide PATH environment variable using the System control panel Advanced System Settings, click on the Environment Variables button). Additionally, Fermilab community-supported instructions for configuring and using PuTTY with Windows are available here.
By default the Ubuntu installer makes the first user account created at install time a member of that sudo group and your account probably isn't, which is most likely what makes the previous administrators account more privileged than yours.
