Oracle Database Express Edition (XE)

I would like to down load and install 11g XE beta but I do not know if it will install and run on my 64 bid Windows machine.

I had trouble with the 10 G XE trying to down load it on 64 bits.

If I cannot use it on 64 bits could I make it work if I down load Unbuntu Linux?
