The Sibelius Forum

Thanks - Using the "Run as an administrator" worked, though I can't see why it's not running as an administrator anyway, as the only account on the computer the admin one.

I have recently upgraded my computer from one running XP and Sibelius 3 to one running Windows 10 and Sibelius 7. I copied all the scores from the old computer over to the new one, but I can't open any of them in Sibelius 7: it says I don't have permission to do it. How do I change these permissions?
