You will need to remove the Enfold program folder and a couple of other files and folders, and then reinstall Enfold. The files you need to remove are:
For Macintosh Users:
/Applications/Adobe Illustrator (CS3, CS4 & CS5.x) ->EskoArtwork
/Applications/Adobe Illustrator (CS3, CS4 & CS5.x)/Plug-ins ->EskoArtwork and Strata
NOTE: In older versions of Strata Enfold 3D CX, the folders are named "Esko-Graphics" rather than "EskoArtwork."
Strata Enfold 3D CX program folder
Enfold 3D CX Sample Files.pkg
Strata Enfold 3D CX.pkg
Essential Files.pkg or Licensing.pkg If you find one or both of these files, remove them.
NOTE: Older versions of Strata Enfold 3D CX also installed a receipt called "Essential Files.pkg". You should remove this receipt if it is present.
For Windows Users:
Run the Uninstaller Control Panel to remove the program.
