I am trying to create an unattended installation of Visio 2008. I am installing on a computer running Windows 7 x64 Enterprise. If I try to install Visual Studio manually, the installation completes succesfully, but if I try to install with an unattend file the installation failes.. I have created the unattend file like this : [VISUAL STUDIO SETUP FOLDER]\setup\Setup.exe /createunattend [PATH TO INI FILE TO BE CREATED], and when I try to start an unattended installation I run this command : [VISUAL STUDIO SETUP FOLDER]\setup\Setup.exe /unattendfile [PATH TO INI FILE]. Tha installation starts and seems to do some work for a while, but when the installation finishes (without any errors) Visio 2008 is not installed on the computer.. What am I doing wrong ? Can anybody please help me ?
