It sounds like you installed the CS5.5 trial at some point. You should be able to uninstall it through Control Panel, but yoiu may have to reinstall CS5 again as well to fix common files.
Hi Peter, thank you. I think I have to unistall the entire suite, because in the control panel/applications it appear "Adobe Creative suite design premium" packed whit no possibility to select the components.
That sounds right, but you can try running the installer and pick Change to see if it will remove just selected parts.
Great! I will do so, unfortunately I am out from my studio and I have not the disc; I will know You about when I've tried.
Thank you more
Hi Peter,I am happy to inform You that the suite where re installed succesfully
