This installs the FLEXnet license manager which is necessary for activating a personal license. This is normally installed automatically, but Geneious will tell you if need to run this when you activate your license. Only an administrator on your computer can do this but it only needs to be done once from one user account. Once this has been done, any non-admin user can activate their license on the machine. The admin should not activate licenses for users as this may prevent the user from activating the license in their own account.
