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 PuTTY 0.75 (64-bit).

What's new in this version:

- Security fix: on Windows, a server could DoS the whole Windows GUI by telling the PuTTY window to change its title repeatedly at high speed
- Pageant now supports loading a key still encrypted, and decrypting it later by prompting for the passphrase on first use
- Upgraded default SSH key fingerprint format to OpenSSH-style SHA-256
- Upgraded private key file format to PPK3, with improved passphrase hashing and no use of SHA-1
- Terminal now supports ESC [ 9 m for strikethrough text
- New protocols: bare ssh-connection layer for use over already-secure IPC channels, and SUPDUP for talking to very old systems such as PDP-10s
- PuTTYgen now supports alternative provable-prime generation algorithm for RSA and DSA
- The Unix tools can now connect directly to a Unix-domain socket
