installing Exchange 2007 Sp3 tells me Exchange 2003 with SP2

Hi there,

We are migrating from Exchange 2003 to 2007. I am trying to install SP3 on Exchange 2007. It gives me the following error: One or More Servers in the existing organization is running Exchange Server 2003 without Service pack 2 or Later.
We have SP2 installed on de Exchange 2003 server. Please Help.

I have added a screen shot.
