From time to time, we have seen some standard company emails as well as non-company emails throw the following message prompt when clicking on or opening: “Language pack installation. To display language characters correctly you need to install the following language pack…


It doesn’t actually matter if the message doesn’t contain any foreign characters. The reason you are seeing this is because the message’s underlying html code contains a tag that is specifying an additional language other than the default being used if it is not installed.

To avoid this message prompt going forward, you can check the option to Never install any language packs and then click Cancel. If you need to undo this, the change can be done by going to HKCU\Software\Microsoft\Internet Explorer and changing W2KLpk value from 0 to 1.

This also applies to Internet Explorer when viewing websites that are encoded using foreign character sets (Outlook 2003 uses IE as its html rendering engine).
