I am unable to install Entourage 2008 Webservices Edition on my MAC. Office 2008 installed just fine. I had to install a security update and that was not easy, but it finally did install so my Web Services would install. It doesn't install no matter how I try, either download or moved on a jump drive. The error message I get is unsble to install to the hard drive, which is the installation point. Could this be an issue with looking for the original install? The Office 2008 was an upgrade and the Web Services was an upgrade also.
