Please check the Help/Getting Started/Quick Start Guide for more information on the Differences between the Regular and Persistant Installations:
The regular runtime version of RhoElements installs to the "\Program Files" directory and can be run immediately after installation. This version will get removed from the device if cold-booted.
The persistent runtime version of RhoElements installs to the "\Application" directory and cannot be run immediately after installation. The purpose of the persistent runtime is to allow RhoElements to remain on the device after being cold booted. On cold-boot, the RhoElements persistent installation is copied to the "\Program Files\RhoElements" directory. Therefore the device must be cold booted to make the persistent installation usable.
Note: The files in \Applications\RhoElements should not be run for normal use as these should be solely for backup purposes. Always run RhoElements from the executable file: "\Program Files\RhoElements\RhoElements.exe".
Does this help with the issue you are facing?
We have tested Installtion of RE with persistent runtime version. It works fine with Rhoelements 220.127.116.11 and 18.104.22.168 build on MC3190 CE 6.0.
Please try to install persistent version of Rhoelements again on mc3190 CE6.0 as per the help file (Mentioned by Rob)
