Cannot save license activation

Hi,

I have installed the IGOR PRO 6.1 on my computer (Mac OS X Lion 10.7.5).
After filling the Serial Number and Activation Key, I clicked on the " Activate Entered License".
However, IGOR shows the panel with "Cannot save license activation because of system error 1579"
I really do not understand what is the meaning of this error.
Hope someone can help me.

Thanks
For some reason Igor can't write to your file system folder in one of the standard expected places.

Is the "Install License for All Users" checkbox showing? Is it checked?

You may need to run the Disk Utility and Repair Disk Permissions on your hard disk.
