I downloaded sPlan_6.0.0.2_full_rus.exe.
But when i installed, there is no option given for language. It was installed in Russian.
Please help me to install in English.

I'm very sorry, it's my fault! It is possible to change only installer language during installation

! But there is very simple solution! Create file sprache.ini in splan folder and type these 2 lines : 1st line - [Sprache] 2nd line - sprache=1. Don't forget square brackets!
Save the file and next time you get English! (If sprache=2 you get France!)
