Question: 1. Can I install a program that I purchased on multiple computers?

2. If I bought a three-user license, can a relative or friend use one of the additional copies?

3. I purchased a program, but no longer need it. Can I give or sell it to someone else?

Answer: In principle, the answer to all of these questions is that the terms of the license agreement are binding, because of copyright, dina dm'alchusa, minhag hamedina, etc. Therefore, you need to read and observe the specifics of the license. Most programs require you to accept the licensing terms before they will install.

1. The license will specify whether it is a single-use or multiple-use license. Some programs offer the option of buying either a single-use or a multiple-use license, for an additional cost. Some single use licenses will still allow the "primary user" to copy the program on his laptop.

2. There does not seem to be a requirement that all three copies be used by the same person.

3. Some licenses will allow you to transfer the program in its entirety to a third party; others are marked "NFR" (not for resale).
