After installing SP1 for SIX, you have two SIX icons displaying on your Desktop. This will only occur on machines where you have loaded the SIX Client under multiple profiles.
This scenario would occur if:
Uninstall the SIX client from all Windows profiles on that machine, then reinstall SIX SP1 under one profile. SP1 for six made a change where the install is not specific to the Windows profile as was the case in previous versions of SIX.
