I recently upgraded from Spyder3Pro to Spyder4Elite and installed the software, calibrated the monitor and everything worked as expected.

This computer has several accounts (wife + kids).  I did the software installation and calibration from my admin account.  I went to my wife's account to make sure the the calibration profile was being loaded and tried to use the SpyderUtility from the Taskbar to enable and disable the calibration and it made no difference.  It looked like the calibration profile was not being used on the other accounts.

I then tried to launch the Spyder4Elite software so I could enable/disable the calibration from the SpyderProof menu instead.  The software wanted me to attach the Colorimeter and go through the activation process all over over again.

Does the software have to activated and and the monitor calibrated on each user account in order for the calibration profile to be loaded?
Why can't this be done automatically for each user account using the calibration profile I generate from my admin account?
