Hi rsam,
Assuming that the PC on which the Adagio programs are installed is also being used as a workstation, do all 3 workstations 'see' the drive with the Adagio programs as E? This is required.
Assuming that the programs are only installed in one place, and not separately on all 3 workstations, then when the updates are installed once, they will not have to be installed anywhere else. There may be a requirement to re-do the workstation installation on the other 2 stations, but this is not required for every update.
Can you confirm what process you are doing on the 'satellite' workstations that is failing? Are you trying to install the upgrade, or run the 'wksetup.exe' workstation setup, or trying to run the updated Adagio program from your shortcut, or something else? And what is the error or problem you are having on the other 2 workstations - is there an error message?
