I think it has been removed from edelivery.
If you have an environment of 126.96.36.199 installed, you may install it from workspace (click on Links after logging in to workspace and you may be able to see financial reporting studio)
yes,I do have an environment of 188.8.131.52 installed,but unfortunately, the fr client menu doesn't exist in the tool ->install list menu of workspace , only has smartview menu.
In order to be able to install the FR studio from Workspace, you should have move the installation file to the appropriate foundation folder (I don't recall at the moment).
You must be able to find the installation file of version 184.108.40.206 at the zip file: Oracle Hyperion Financial Reporting, Fusion Edition Release 220.127.116.11.0 either from e-delivery.
In 18.104.22.168 the FR studio is installed by running the installer(installtool.cmd/installtool.sh) and selecting the FR client .Before that you need to have the files downloaded for 22.214.171.124 :
Oracle Hyperion Enterprise Performance Management System Installer
Hyperion Enterprise Performance Management System Foundation Services Release 126.96.36.199.0 Part 1 of 4
Hyperion Enterprise Performance Management System Foundation Services Release 188.8.131.52.0 Part 2 of 4
Oracle Hyperion Financial Reporting, Fusion Edition Release 184.108.40.206.0
Oracle Hyperion Financial Management, Fusion Edition Release 220.127.116.11.0
These are the required files.Currently you will not get these in the Oracle E-delivery. You need to raise a non-technical Service Request for the files with Oracle for these.
Hope this helps.
You will need the Admin Rights for the user logging into workspace in order to see the "FR Studio" menu item.
