Hi Luca Thank you for the answer. I understand. I my situation I would prefer to have the latest version installed. I can live with some different directories, but 90% will be overwritten with the new version. So do you think I can overinstall the new version to the old one? What about the unsinstall information in system registry and all keys? Will they be overwritten, or stay there to the end of times? Prbably they will stay and only stuff the registry. If so, I guess that uninstalling first, and then instaling a new version is the right choice. Well it looks like I have answered my question as well :)) Thanks regards Pawel
