Nero Burning Rom 9 - Portable (working!!)
Nero 9 Retail EN Portable by Divu | 25.4 MB
This version doesn't need a key or ini file etc. Contains only Nero, no express or other tools. I tested it up to 30 Jan 2010, and got no error.
Tested under XP, XPx64, Vista & Vista Ultimate to work perfectly fine.
This is a standalone executable, no folders needed.
