Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system. Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of PuTTYgen 0.78 (32-bit).

What's new in this version:

- Support for OpenSSH certificates, for both user authentication keys and host keys
- New SSH proxy modes, for running a custom shell command or subsystem on the proxy server instead of forwarding a port through it
- New plugin system to allow a helper program to provide responses in keyboard-interactive authentication, intended to automate one-time password systems
- Support for NTRU Prime post-quantum key exchange
- Support for AES-GCM (in the OpenSSH style rather than RFC 5647)
- Support for more forms of Diffie-Hellman key exchange: new larger integer groups (such as group16 and group18), and support for using those and ECDH with GSSAPI

Fixed:
- the 32-bit Windows build now runs on Windows XP again
- server-controlled window title setting now works again even if the character set is ISO 8859 (or a few other affected single-byte character sets)
- certain forms of OSC escape sequences (sent by some real servers) could cause PuTTY to crash
- the -pwfile/-pw options no longer affect local key passphrase prompts, and no longer suppress Plink's anti-spoofing measures
- Note: installing the 0.78 or later Windows installer will not automatically uninstall 0.77 or earlier, due to a change we've made to work around a bug. We recommend uninstalling the old version first, if possible. If both end up installed, uninstalling both and then re-installing the new version will fix things up.
