    Error upgrading from win 8 to win 8.1 64 bit iso


    PC is an AMD A4 processor with 8 gb RAM, 32 bit operating system, x64 processor with win 8 pro installed.
    When attempting to upgrade to win 8.1 pro 64-bit iso, by clicking Mount> double click Settup, I am getting the following message:
    "This app cannot run on your PC. To find a version for your PC, check with the software publisher".
    If I installed the 32bit iso it works fine.

    Thx

    You can't upgrade to a 64 bit OS from a 32 bit OS. It would require a clean install.

    Thanks for your values reply.

    I have since created a bootable CD from Win 8.1 64 bit ISO but it wanted drivers for the usb dvd drive so I bought a Lexar 16 gb usb stick and used 2 dif freeware and WIndows 7 USB DVD Download tool to create a bootable usb stick from Win 8.1 64 bit iso. Deleted the Primary hdd partition and attempted to install with the bootable usb but every time I get an error:
    Windows cannot install required files. This file may be corrupt or missing. Make sure all files required for installation are availableand restart the installation. Error code: 0x80070570

    Where did you get the ISO file from? If it was a download, try downloading it again, and make a new bootable thumb drive.
