Hi,

I have my product key when i purchased the system for ms office 2007 for vista. But when i try to enter the product key which is in the sticker is not accepted in the system. It is giving invalid product key, try to enter again message. Please help me to solve this problem.

Note: when i was installed office 2007 it asked me many times to enter the product key. But i skiped many times and finally today i got the error the "Modification is not allowed because the selection is locked" message.

Regards
Ramesh
