RST cannot show email function

Hello,

I would like to ask the query that I have two same spec hp8300 sff PC (7 series / C216 , with MSFT Win7 Pro Eng(US) / Win7 Pro T.CHI),

when RST ver. 12.5.0.1066 operate , T.Chi version can show email function while Eng(US) cannot.

What I should do with the software (or even any change in Windows configuration) before I commit 780 PC (including Lenovo M91p later) for auto mail alert soon?

Thanks a lot.
