The preferred way to to update GhostScript is through the Windows installer, but this occasional fails if files are open which will lock its folder and prevent changes. You can shut down all running instances or reboot the computer and then update. Or you can run the installer from the command line with the Silent update option:
- Download the installer.
- Copy the installer to the computer and run it with the Silent (uppercase S) option:./gs1000w64 /S
- Check the “/Program Files” folder to see if there is a gs10.* folder to confirm installation.
