[Qt-creator] How to set version in tools/option

[Arun]

Hi All,
Please guide how to define version for QT Creater.

I get error as:

No valid Qt version set. Set one in Tools/Options 
Error while building project GUIAPP

When executing build step 'QMake'

Canceled build.



I use QT with minGW in windows XP.



Thanks in advance

regards,
arun
