how can i add my own key?

I have generate free pro key for non comercial use. But there’s no option to put it in program.
Path  Help > License does not open any option to write it in.

I have version 7.2.35595.0

In Menu > Help > License , click on the Activate button then enter the key. If the application was activated using another key, first click on Deactivate.

I alredy wrote, that there is no such option i my eMclient, there is no Activate option…

Hi Gary, 
Just curious…

OP wrote : “I have generate free pro key for non comercial use.” 

Since when does eM client provide a “free pro key” ?
I thought it was either Free or  Pro…

Actually you wrote that “Help > License does not open any option”. What you actually meant is that there is no Help > License option. These are two different things.

Thats why I put prtsc, to be clear.
