MaxDB 7.6 ECC 5 installation

Hello all

I am doing an installation for ECC 5. So I install the CI and then the DB. And at "MaxDB server installation, there is an error and the log sdbinst says "

package "SQLDBC 7600" exists more than once in installation kit

installation exited abnormally  at Mo, Dec 02, 2013 at 19:52:27"

Any idea where this is failing? How can I verify the package?

Thanks in advance

Cheers - Ray
