There's an easy way to get the manual and help file for easySoft in Polish language.
Switch easySoft to Polish language an use "?"-menu to open help or easyE4 manual.
Choose "Save file as..." in your PDF-viewer.
Btw. Your Polish collegue is able to install easySoft as Demo version. So he can read the manuals within easySoft, too.
