Be sure to disable security and virus scanning software, and quit as many applications as possible to reduce the probability of these programs interfering with the update process. As always, be sure to have a full backup of your system and data in a readily restorable state before updating, especially if your work highly depends on Photoshop.
If you have problems with the installation or the update, please let us know.
