I simply add a file system link into Photoshop presets\scripts\ all versions of Photoshop use the same copies of Scripts and Plug-ins on my machine. I have CS2, CS6, CC, CC 2014, CC 2015, CC 2015.5 and CC 2017 installed. Some things do not work in CS2 its very old. CC 2014 is my goto version of Photoshop. File System links in Windows are also known as Shortcuts.
