Updates are defined as enhancements to the original package that you purchased. Once the package has been updated, the old package should be destroyed or used solely as a backup. Again, it depends on what the software licence says. Some licences say that software can be used both at home and at the office. Some say that the program can be used on several machines, provided that no two are running at the same time.
Some programs are very restrictive, and say that the program can only be used on one machine.
If you donUt have access to the licence, or if you find it ambiguous or unclear, make sure you check with someone such as a technical support person, about the details before you copy anything. If you find yourself in a situation like this and donUt know the answer, someone else does. Worth the Risk.
