Hi. I am trying to upgrade an existing old machine from Win10 32bit to 64bit. It does what we need it to and only runs into problems with memory being capped at 4GB. The upgrade to 64bit is to get over that limitation. The motherboard is old, an Asus P7P55D, but this does support 64 bit OS and others report it running reasonably well with Win 10 x64 on it. I do realise this is not just an upgrade, it is a complete clean install so I know it completely wipes the old version and all data too. Data is taken care of and backed up ready to go.


I have already overcome a bevvy of problems with the installation. It won't boot from memory sticks despite the Boot order being correct. That may be due to memory stick limits as I am having to use a 256GB stick in USB 3.0. I've tried going direct to the stick from Media Creation Tool and also from Rufus but no joy either way. I have burnt an ISO DVD and at first it would not respond to the keyboard press confirming 'Boot from DVD'. Eventually a simple USB/PS4 convertor cured that. Now I have the machine booting from DVD but it gets as far as the version selection and all it offers are x86 options.


On downloading the installer I definitely selected X64 only in Media Creator Tool, the download was doene on an up to date X64 bit machine anyway so selecting 32bit by accident shouldn't happen. A DSIM query of the file shows that all versions are there with file sizes of around 15GB. This is higher than I have previously seen, (around 10GB), but I am assuming this shows that both the 32bit and 64bit versions of each are present.


Am I trying to fly without wings here? Or is there perhaps an older version available which would install? Any advice is welcome.
