My PC goes through the process of installation but at the end keeps telling me that 7 cannot be installed. I have followed the instructions and getting to he stage where I want to throw my PC through the window. I have do a clean install on my laptop from XP Pro with no problems can anyone help please.

Install & run Windows 7 Upgrade Advisor (download from THIS link). See what it advise and post back. i_Xp/VistaUser

What Win 7 Upgrade package did you buy? You have Vista Home Premium which tells me that you need Windows 7 Home premium Upgrade disk. If you have any other upgrade disk then windows will tell you that it cannot complete the upgrade. The reason is simply that it is a downgrade and that does not happen in the world of Microsoft. Vista Home Premium=Windows 7 Home premium upgrade Vista Business PC=Windows 7 Professional upgrade Vista Ultimate=Windows 7 Ultimate upgrade This should give you a guide as to which upgrade disk to purchase in relation to what you already have on your machine.

terii, great answer!!! Some HELP in posting on Computing.net plus free progs and instructions Cheers
