Windows 7: Unable to install Windows 7 64

06 Oct 2010   #11

Windows 7 Ultimate x64

Your 64-bit key is compatible with 32-bit Windows 7. It doesn't matter which one is installed it will activate either one as long as only one is installed at a time. You probably could download the bits somewhere and use your key to activate. If you have problems activating use the phone activation and speak to someone after trying automatic phone activation. Explain to them what happened and I am sure they will assist you in activating your OS. They are not out to get someone and make them spend more money, they are just strict on piracy and you have a legal version. Don't buy a new one for 32-bit!!!!!!

PS. I looked up your CPU and the Pentium D's are 64-bit compatible. You should be able to install Windows 7 x64 on your machine. You may need to update your BIOS before continuing.

You do not need to buy another Win7 to get 32 bit. You are entitled under the EULA to use either 32-or 64-bit with each license and can switch back and forth any time you want as long as you're only using one at a time.

You have only limited yourself by buying OEM since it become locked to the hardware and cannot be moved to another machine without an exception for good cause being granted by MS activation agents. So if you have the ability to return it, then it would only need to be to buy retail instead to get more flexibility. If you have any Vista/XP there then you qualify for Upgrade version which is about the same price.

What you need to do is find a 32 bit installer for your version. It doesn't matter if it is OEM since that is in the Product Key and not the installer.

Take the HD back to the machine you installed Win7 on and in Device Manager remove all the major drivers. Do not restart when prompted, just shut down and move HD back to problem machine to see if it then starts.

Next wipe the HD first before install using this method: SSD / HDD : Optimize for Windows Reinstallation At the end of the partitioning commands given add Select Partition 1, Format, then Active.
