On a Mac you can remove PortraitPro Body by simply moving it into the Trash. Then open the Finder view, then click on Go. For macOS Lion, hold down the Option key (ALT on non-Mac keyboards) and click on Library, and then Preferences. Earlier versions of macOS will have the Library folder visible in the Home Folder. Now scroll down and look for anything containing the name "PortraitProBody" and also move it to the Trash. In the Finder view, go to your home folder. Then click on Library, then Application Support and then Anthropics . Move to trash the PortraitProBody folder within the Anthropics folder.
On Windows Vista, 7, 8, 10 it can be removed by clicking the start button and typing "remove programs" and the option "Add or remove programs" will come up. Choose this and follow the instructions.
Another way to remove the software is to go to the "C:\Program Files" directory where PortraitPro Body was installed and finding the folder, normally with a name such as "PortraitPro Body 3". Now run the program in this folder called "unins000.exe" and the software will be removed.
