I'd like to install Oracle Database Express Edition 11g Release 2 for Windows, but all I have is a 64-bit Windows machine (running Windows 7).
Will a 64-bit Windows version be available in the near future? If not, what kind of problems can I expect if I install the 32-bit version?
I would not hold breath there will be 11G XE for 64bit windows.
You could expect problems, that others have workaround when installing 32bit version of database.
What I would do is take VirtualBox and install e.g. supported Linux there and XE database
