To get R to install we had to move the folder (Oracle Data Visualization Desktop) to the C Root. Then rename the folder (Oracle Data Visualization Desktop) to (OracleDataVisualizationDesktop). R then did install. It is installed at "Program Files / R" . However, when I run DV and try to use the AA. It tells me I need to install it (R).
If you have installed DV Desktop and then subsequently moved the directories/subdirectors using OS commands then that's not something I have done - but as it is a fairly quick process, I would just think about just re-installing it where you want it.
