Vista upgrade issue.

[grumpy]

Greetings, I'm running a clean NTFS installation of Vista Business on an HP/Compaq 8510p laptop in a domain environment. When I run Windows 7 Enterprise "Install Now" from DVD the screen will display "setup is copying temporary files" followed by "setup is starting" then a pop up dialog box called "Install Windows" stating "Windows setup cannot determine if this computer supports installing this version of windows"

Windows Upgrade Advisor runs clean stating Upgrade available.

The time between the copying screen and starting setup is seconds where-as if I boot into the DVD the copying process takes minutes.

I'm performing this as a precursor to company wide upgrade and the outcome will have a major affect on our direction.
Thanks in advance.

Before we begin, can you please fill out your system specs, so we know what hardware/OS version .. 32 or 64bit we're dealing with??

Thanks..

Hi Grumpy and welcome to SevenForums.

This may be what is causing your issue ...

Upgrading from Vista to Windows 7

Pros: Unlike XP, Vista users do get a direct upgrade path to Windows 7, so your files and apps should migrate to Win7 without any problems. (You should always backup before upgrading to be safe, and just to hedge your bets, you may also still want to dual boot Vista and Windows 7 rather than installing Windows 7 over Vista.) Vista users will also get the cheaper upgrade price.
Cons: It probably won't affect most users, but the Vista-to-Windows-7 upgrade paths are actually limited by version in the following ways:

• Windows Vista Home Premium to Windows 7 Home Premium
• Windows Vista Business to Windows 7 Professional
• Windows Vista Ultimate to Windows 7 Ultimate

If you don't follow one of those three upgrade paths, you'll have to perform a fresh install

The info is quite old so you may wish to check this with Microsoft

I've tried both version with the same results.
Specs updated.
