I encountered a win Live Mail error after the upgraded to Windows 8.1 pro. Whenever I open live mail I get a message box saying that a component is missing (.Net 3.5) and gives me the option to install it or skip it. Tried to downloade separately, enable windos component, but all failed with the same error, ending, if i remember, in 736CC

I go for install and it downloads/installs but it ends with an error and after that the windows live mail opens fine but I am not able to send/reply/forward/create new emails, there is all the time the same error: "problem  occurred while trying to open this message. A problem has occurred. Please try again". 

Tried to do the repair windwos live eseentials from control panel, but the error persists.

I am able to receive / view emails fine (pop or outlook)

Your help is appreciated.

Thank you,

Adrian
