i downloaded ubuntu-7.04-alternate-amd64.iso
simply because I have an AMD64, I dont want to use i386.
I checked the checksum. match.
I put amd64.iso file in folder with Wubi-7.04.03.exe
I do install. every time it tries downloading the i386.iso
64 bits are not supported at the moment, you can still install 32 bits.
because we would need to compile and maintain a second initrd, and since I (and the other devs) do not have a 64 bit machines that is not going to happen.
Of course if someone wanted to donate a 64 bit machine I would reconsider
That said once wubi is included with gutsy it will come to all archs supported by ubuntu.
yep we worked on those, have the metalinks ready thanks to Hampusw (who has a 64bit machine), but did not follow up, as mentioned the required step is to have a second initrd secifically compiled for such machines.
My view is to try wubi32 bit, if you like what you see, do a real 64 bit installation.
