  • KeyShot | KeyShot Plugins
    • This can happen to any version of the KeyShot and the KeyShot plugin.


  • The would-be that KeyShot is installed in a different location than the Plugin is installed. 
    • This can happen as KeyShot installed "Just for Me" will install into a different directory.
      • The install can end up at "C:\Users\UserName\AppData\Local\KeyShot ##\
      • The plugin will normally install to "C:\Program Files\KeyShot ##\Plugins\
