I cannot activate license on Windows XP
Posted by Olivia Rust on 12 June 2018 18:29

Microsoft has officially ended support for Windows XP on April 8, 2014. Unfortunately, this means that the security protocols from the last service update are no longer up to current standard. So when you try to activate the license after the eM Client trial, you will encounter an error message instead, because the request sent from Windows XP, unfortunately, doesn't arrive at our licensing system.

A problem has occurred when contacting the licensing server:

The underlying connection was closed:  an unexpected error occurred on a send.

We have created a compatibility version for XP which allows the connection, but please be aware that this version will not be updated in the future. Please send us a message to info@emclient.com if you are interested in this version.
