Per this article, we had to change Bloomberg to use Current User Registry Directory Hive for it to work in Terminal server Enviroments

Well this process breaks BQNT aka BQuant! The only remote fix for this is switch to VDI !

Due to non-persistent VDI session, serial number was installed on CU in order to prevent the serial number from getting deleted each time when you log out of the machine. However, installing the serial number on CU will affect BQNT installation, even if we manage to install BQNT successfully, we won’t be able to run BQNT due to limitation which is expected. Therefore, we suggest to install the terminal on a local machine instead of virtual environment.
