I saw some youtube comments about same problem.
"I got 5 files over the oracle link. Downloaded all 5 files but when trying to extract 1st file. I am getting error that file is not valid to extract. Anyone has any idea ?"
I'm receiving unexpected end of data error with 7-Zip.
I tried on different PC but result is same.
shows a link named "ODI 12c Getting Started VM Installation Guide"
Check page 6 of that PDF to extract the VM
I checked the PDF, I'm doing same operations.
There might be a problem for installation files.
Thanks for support.
I have downloaded myself the 5 zip files and extracted using 7-zip.
The extraction was successful.
I think the files were not downloaded properly or are not extracted as per page 6 from pdf.
