Adobe Creative Suite Design Premium

Hello, I bought a new Mac and I'm trying to install Adobe Creative Suite Design Premium CS5.

I used to work with it on my former Mac but today it seems impossible to start the installation.

When trying to do so, I receive the error message (sorry in dutch) : "Verwijder schijfkopiebestand".

Can s.o. please help me in solving this issue?

Thank you,

Hilde
