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 0.64.

What's new in this version:

- Security fix: PuTTY no longer retains the private half of users' keys in memory by mistake after authenticating with them. See private-key-not-wiped-2. (Sorry! We thought we'd fixed that in 0.63, but missed one.)
- Support for SSH connection sharing, so that multiple instances of PuTTY to the same host can share a single SSH connection instead of all having to log in independently.
- Command-line and configuration option to specify the expected host key(s).
- Defaults change: PuTTY now defaults to SSH-2 only, instead of its previous default of SSH-2 preferred.
- Local socket errors in port-forwarded connections are now recorded in the PuTTY Event Log.
- Bug fix: repeat key exchanges in the middle of an SSH session now never cause an annoying interactive host key prompt.
- Bug fix: reset the bolded-text default setting back to what it used to be. (0.63 set it to something wrong, as a side effect of refactoring.)
- Bug fix: IPv6 literals are handled sensibly throughout the suite, if you enclose them in square brackets to prevent the colons being mistaken for a :port suffix.
- Bug fix: IPv6 dynamic port forwardings should work again.
