Think very carefully before upgrading. This installation disregards all rules of security and steals your credentials to install unannounced applications. It is a massive failure of security etiquette. There are posts in the specific Access forum about this but in summary you will finish up with several things installed that you have not asked for or authorised. You will have a server account associated with your Parallels logon information. Read the posts before upgrading and decide if you are happy to do this. For me it is a complete disaster.
