Where Does nVision 3-tier Client Install Program Files on Windows?

In the past we have been able to give users nVision 3-tier Client access on a Citrix VDI using PVDs assigned to a user ID, which allowed the user to retain an nVision installation and personal configuration.

With the upgrade of the Citrix VDI the use of PVDs has been discontinued, and the only personal space that is accessible is the C:\users\<user id> directory. 

We would like to know where the 3-tier client installs the handful of files used to operate, so we can attempt to point the read/write files and directories to build and exist under the user's personal directory.
