Can we install 32 bit and 64 bit versions of developer preview on the same 64 bit machine?

    Question

  • The machine already has 32 bit developer preview installed. Now we are trying to install 64 bit dev preview on the same machine. During preparing step, we are getting the error "Windows cannot be installed on this hardware".

    The system is 64 bit since we also have Win7-Home Premium - 64bit installed on the same machine.

  • Hey Lucky Shah,

     

    Since you are getting this error message during the preparation stage, you may have a piece of hardware that isn't working properly with the drivers that are included with the installation. Try disconnecting all external hardware (printer, fax, scanner, webcam, headset, speakers, etc.) from your computer and try the installation again.

     

    Hope that helps.

  • You have to boot from the DVD and start the install that way -- you
    cannot start the 64-bit install while booted into a 32-bit OS.

  • We have a bootable USB Drive that we connected to this machine, booted the machine, selected USB Device as the boot device and the installation started by asking the partition.

    We had created a partition of 20GB which we pointed when the installation asked for it. The installation got completed, but during the preparation stage, it threw the error.

  • Hi lucky,

    please start the operation again, once you get the error message, click on Advanced options, select Format to format the drive selected. I do hope you will be able to proceed with the rest of the installation once the chosen drive is formatted. You may manually format the drive to NTFS simply by right clicking and selecting Format from among the many other given options. Hope this works for you.

  • Are you trying to dual boot or just install the 64-bit version of Windows Developer Preview?
    Is your system 64-bit capable?

    If you have a 64-bit system, follow the steps from Irfanfare and format the partition and start the install.
