Please read the following instructions carefully in order to determine the proper upgrade steps for your system.

If you are upgrading from ZBrush 4R7 or earlier, please follow the full instructions here. Your installation of ZBrush 4R8 will be the P2 version from the outset.

If you have already upgraded to ZBrush 4R8 or 4R8 P1, with ZBrush closed, please browse to your ZBrush 4R8 folder and run the ZUpgrader application found there. (Do not run "Update" or "Updater" or anything else. You must run ZUpgrader.) This will update your 4R8 installation to 4R8 P2. You will not need to reactivate ZBrush after updating.

  • If you encounter issues with the ZUpgrader, please download the appropriate updater for your platform: Mac OS X or Windows. After downloading, this file can be run from anywhere on your system, including the Downloads folder. It will update you to ZBrush 4R8 P2 with no need to activate afterward.
  • If for some reason neither updater method will work for you -- or if you simply prefer to have a completely fresh ZBrush 4R8 P2 installation -- please uninstall ZBrush 4R8 and then install ZBrush 4R8 P1 using the full installer found at Step 2 here. You do not need to deactivate 4R8 before doing this but you will need to do a new Web Activation after installing to generate a replacement activation code.
