Administrative rights are required to install and uninstall STarStation. All STarStation users must be set up as Power Users in Windows 2000 to perform Calibrations or act as the STarStation Administrator.

Without the necessary operating system access priveliges StarStation cannot successfully perform calibration , control verfication (IS systems only) or correctly save acquisition data to the users STarStation samples directory.

You must have either Power User or Admin access to the operating system when you log on to perform calibrations and to run assays.
STarSTation software checks for this at startup and displays a warning message as shown below

ACS are aware of situations were folder access can be modified to deny write access to certain folders that STarStation 2.0 requires access to , despite the user having Power User priveliges.

Access to the following folder locations are required for calibration information to be saved on the system.

b) C:\Program Files\Luminex\LXRLibrary\Log

c) C:\Program Files\Applied Cytometry Systems\STarStation 2.0\

d) The registry
