Can I remove one of Nero 6 Ultra Edition or NeroVision Express 3?

…but since it’s Nero I put here. :confused:

Clearing space on hard drive. Have Nero 6 Ultra Edition AND NeroVision Express 3. Only use Nero to burn audio CD’s and video VCD’s. That’s it. Don’t use the Viewer, photoshop, etc. Can I get rid of one of these? AND if I can, can I copy the deleted program to a floppy disc (probably won’t fit, right?) or CD should I want to reinstall later?
