Virtual Desktop Infrastructure (VDI) allows users to use a remote computers as the host for their local desktop—including systems like Citrix and Microsoft’s Remote Desktop RDP/RDS server—and it is not uncommon for each session to be a brand new instance of the virtualized computer, booted from scratch.
EstateVal and the other EVP Office applications store their user-specific information in the %APPDATA%\EVP Systems\ directory, meaning that if that particular path is preserved across VDI instances per user, their Account Information File (EVPS.DT0) and preference (.INI) files will be present on any new instances.
If the directory is not preserved, the instance-creation process provided by the VDI system will need to run a script that copies appropriate versions of the files to the location. This will give the user permission to run evaluations (via the Account Information File) and start up with specific settings (via the app-specific .INI files).
