Allow other users when upgrading from version 8 to 9

When I originally installed Parallels 8 I did not allow access to Windows to other users on my iMac. I am now upgrading to Parallels 9 and want to enable another user on my computer to access my Windows programs. Will I be prompted to allow other users when I install the Parallels 9 upgrade or will I have to go into Parallels 9 later to allow this. If I have to go in later, how do i do it.
