Run RAD/Eclipse with the -nl argument followed by the language en_US, e.g.:
eclipse.exe -nl en_US
or add the variable
-Duser.language=en
at eclipse.ini file.
Both eclipse.exe and eclipse.ini are located in default IDE installation directory, .e.g.:

Solution founded here.
Today I had no electricity. Laptop is powered by embeded battery too,
but router & modem no… :/ From time to time I need an english dictionary.
Generally I use online dicts (such as google translate or dict.pl), but if
I didn’t have internet connection they’re useless… In order to avoid this
problem in future I founded offline dictionary for my Android Device.
Off course it doesn’t have translations to my native polish language, but it’s
better than none
