Oracle installation on Windows 64 bit with Intel Xeon

Hi!

we have Windows Enterprise Server SP2 <b>64 bit</b> with <b>Intel Xeon</b> processor and would like to install the SOLMAN with Oracle.

According to the original Oracle-DVD from SAP there are only three possible choise entries:

a) AMD64

b) IA64

c) I386

But I have the feeeling it should be one choice like "x86" is not?

Which one should we apply?

The I386 can be installed indeed, but we are getting the error during the SAPINST-Installation "Oracle software not installed". I thought this entry was only for 32 bit?

The IA63 Bit can not be installed.

<b>Only the AMD64 we could install. But the question is, whether AMD is the same to Intel Xeon?</b>

Thank you very much for any useful help/comments...

regards
