Never get a release from edelivery unless it is the only option. I would always recommend searching for the latest release on My Oracle Support. For 32bit Oracle on a 64bit OS, I would probably go for the 32bit version of OGG... however, it's a very uncommon platform for a product like GoldenGate, I don't think there are many production environments running Windows 7 64bit with 32bit Oracle.
The build you will want would be named similar to this:
Oracle GoldenGate V126.96.36.199.1 for Oracle 11g on Windows 2003, 2008
Thanks a lot Nick
Where can I download installers from MOS? I do not see any installer download tab page inside it.
Unlike OTN and edelivery you find lots of installers there.
Can I install both 32bit and 64bit Oracle in my win7 laptop?
