1. I am customer of Ionos, formerly 1&1, who host my email address. 2. Ionos have advised me I will be unable to download emails from their server after 25 April unless the email program supports TLS1.2 or higher and they said Thunderbird version 52.00 supported TLS1.2 or higher. 3. I have 2 PCs with Windows XP SP3 and 1 laptop with Windows Vista. Ionos say the only email program I will be able to use after 25 April using the latter 3 devices to download emails from their server is Thunderbird version 52.00. 4. Is there now any means by which one may install Thunderbird version 52.00 onto a PC with Windows XP SP3 or, alternatively, a laptop with Windows Vista?
