Thanks for your reply.
I tried many time using my network and it is giving me the same error how many times i try.
Hope issue with Oracle Site.
Can you try and let me know if it is working fine for you.
Please, apply the Oracle note:
OBIEE 12C Will Not Installl on Windows 64 bit platform with "Could not extract the archive since its corrupted. Error Code = 1" - 2097491.1
Are you suggesting me to add an SR with Oracle Techsupport.If so i don't have any Support Identifier to create a ticket.
So could you please suggest..
