Don't select anything in specific now.
Just select everything, and when you get to the download page, refer below doc:
R12.2: How To Create the Stage In Preparation For Installation (Doc ID 1596433.1)
The above doc shows what all files you need to pick for installing 12.2.0.
Ensure, you select only those files for installation. Else, you may run into issues.
Hope this helps!!!
You cannot directly install 12.2.5
You will need to install 12.2.0 and then apply the 12.2.5 RUP
And why those "(12.2.5), 59 files" are for?
Those are the NLS Files for 12.2.5.
These will be needed in case of additional languages.
You will not need those files for 12.2 installation.
As I said before, download only those files as per the Doc ID provided earlier to create stage area for installation.
The files in 12.2.5 option are not just NLS related files.
This option includes the following:
Rapid Install 12.2
Oracle RDBMS 126.96.36.199
Oracle EBS 12.2.5 Update Pack
12.2.5 Documentation Library
You will need the update pack to upgrade to 12.2.5.
You will also need the 188.8.131.52 database files if you are going to upgrade the database before you go to 12.2.5. If you plan to upgrade the database to 12c then you don't need these files.
