About

Putty.png

PuTTY is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. It can also connect to a serial port.

Version 0.74.0.0

PuTTY is now available as a MSI installer, but previously was an executable. This means to script the removal of any version we need to mitigate for each possibility. There are particular requirements for the EXE removal, oddly that putty.exe must be deleted before the uninstall starts in order to make it silent.


Assumptions

This document assumes you are familiar with the use of a Windows Administrator Command Prompt. It also assumes your copy of the PSADT is preconfigured to write logs to C:\ProgramData\Logs.


Obtain Package Source

PuTTY is freely available for download.

Please note the script contains Pre-installation logic to detect and uninstall any legacy version it encounters and logs the version number. Removes any version of PuTTY, whether 32 or 64-bit. A variable array is used to ensure both Program Files locations are checked. A variable is also used to determine the name of the uninstaller executable (used in older versions), as this can vary between unins000.exe and unins001.exe, depending upon how many times the software has been previously installed and removed.

Relevant extracts from the script are as follows:
