"It's a burned copy of the legal install disk" Unless your employer transferred the licence to you and renounced his rights to it, or included your use of it in a multi-platform licence from Adobe, it is an illegal copy, and illegal for you to install on your machine. Serial numbers prove nothing. Most Adobe and other "WAREZ" comes with a valid serial number and are in fact either full CD copies or "rips" of fully licenced originals. "Warez" is meerly another name for pirated software. STORM
