PS: I installed it on my another mac machine with photoshop cs3 and it was ok.

Which system was installed first, machine with CS3 or CS5. If it was the CS3 then the situation is due to a license issue. If it was with the CS5 machine, we need a little more info.
In either case, it is recommended that you open a support ticket and explain what has happened and someone will get back with you ASAP.
