Upgrading windows vista 64bit

Yes you can however HP only supports Windows XP (32-Bit), Windows Vista (32 and 64 Bit) No official support for windows 7.

However Most modern PC's will run windows 7 and most drivers are available. Upgrade at your own risk.... There might be some drivers that you wont find and may cause problems with your PC.

But why upgrade to 64bit if you are not upgrading memory to 4GB+?

See Windows 7 system requirements Microsoft Windows

Open Device Manager, Uninstall the Graphic Card and driver, reboot the machine, allow Windows 7 to apply the generic driver, Open Windows Updates and run. OR, open Device Manager, display adapter, update Graphics adapter. OR, Use the eMachine windows vista 64 bit drivers. Download the Windows Vista 64bit driver and Save , open Properties, change compatibility to Windows 7.

If your Acer has a 32 bit processor then you cannot upgrade to a 64 bit Windows operating system. In this case you can upgrade to 32 bit Windows 7

Hello kelvinvu, according to the information that I gathered from this computer model, it has Windows Vista 32 bit home premium installed on it. Windows XP is an older operating system so you can't "upgrade" to it. You could however install a fresh copy (more likely completely erasing all your previous information on vista and data files) or you could upgrade to Windows 7. Since you are using "Windows Vista 32 bit home premium", you have to upgrade to "Windows 7 32 bit home premium" or better. So if you were trying to "upgrade" to Windows 7 Home Basic, it will not allow that since it considers that a downgrade in the Operating System. You should actually be able to pop in the Windows 7 Home Premium CD while vista is running and start the upgrade process pretty painlessly that way. Just access the CD and walk through the menus for upgrading Vista to Windows 7. As a reminder, you must use the 32 bit discs. If you try and use the 64 bit discs (a different operating system as far as windows is concerned) you will have to go through the same process of installing a new version of windows (not upgrade). I hope this has solved your specific problem kelvinvu, have a great day!

I think i know what happened. Windows Upgrade Advisor by the name itself it means that there has to be an older version present on teh system to be UPGRADED. Have you tried installing WIN7 with OKR v6.0 then downloading OKR v7.0 try not uninstalling the OKR v6.0

>I chose not to charge you for rhis since this is more of a suggestion than a resolution... i would like to know what happened after trying this, i would greatly appreciate your comment on this, thanks!

AutoCAD 2004 and Windows 7 are NOT compatible. You will need to upgrade to AutoCAD 2010 either 32-bit or 64-bit. Even with the upgrade, there are known limitation issues.

THis is because vista and older palms aren't compatible. You need to transfer via bluetooth or upgrade your palm.

If your computer meets the hardware compatibility requirements,

purchase Windows Vista Home Basic 32-Bit at this link for under

$90.00. Install it as an upgrade and your existing files will be moved

to a folder named Windows.old. If you choose to upgrade bear in

mind that Vista puts your system resources under a heavier load

so you may want to add more memory to your machine.

most will have to be run in compatibility mode. movies on cd & dvd probably won't burn to cd (or run at all). they're too old for the manufacturer to post patches for vista support.

if the software is already installed on a pc, run the upgrade advisor to get more info on compatibility.

when you upgrade to vista, there will be a summary page as to what programmes and hardware are not supported just before the initial installation takes place, or download this vista upgrade advisor first http://www.microsoft.com/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx
