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 0.84 (64-bit).

What's new in this version:

- Security issue: fixed a remotely triggerable double-free in RSA key exchange. (We don't know of any way it is exploitable to execute code.)
- Minor security issue: fixed a remotely triggerable crash in NIST ECDSA signature verification. (An assertion failure – definitely not exploitable to execute code.)
- Minor security issue: fixed marking of Telnet and Rlogin session data with a trust sigil after you authenticated to a proxy (possibly allowing a server to spoof a repeat proxy password prompt)
- Ability to run a specified command before starting the connection, e.g. to perform wake-on-LAN or a port knock
- On Unix: display 'pre-edit text', showing the progress of using multiple keystrokes to compose a single Unicode character
- On Unix: improved support for to running the GUI tools on Wayland (fixed startup issues and tuned performance)

Fixed:
- configuring a SSH certificate authority on Unix would fail unless you manually made a config directory
- spurious "Network error: Socket is not connected" when authenticating to some HTTP proxies
- disabling cursor blinking in the Windows Control Panel but enabling it in PuTTY would lead to a tight loop
