Hi If you log into the App store on each mac with your Apple ID you used to purchase FCP and select "Purchased" you will see the INSTALL button on the right. Simply hit this and let it download and install. When you have installed it there are large amounts of extra files to download to complete the installation which will be optional for you to download. I've not tried it on mac clients but Profile Manager if you set it up should also let you install to your clients via VPP. Or you can make packages and distribute to your mac clients using Apple Remote Desktop
