However, the copy can only be used if the original software is destroyed or fails to work. When the original is given away, the backup copy must also be given with the original or destroyed. Lack of copy-protection does not constitute permission to copy software without authorization of the software copyright owner. Software acquired by colleges and universities is usually covered by licenses. Such licenses cover software whether installed on stand-alone or networked systems, whether in private offices and rooms, or in public clusters and laboratories.
Some institutional licenses permit copying for certain purposes.
The license may limit copying as well. Consult your campus authorities to be sure about the permissible use of a particular software product. Some licenses may even restrict the use of a copy to a specific machine, even if you own more than one system. In general, licenses usually do not allow the software to be installed or resident on more than one machine, or to run the software simultaneously on two or more machines. Historically, the Copyright Law was modified to permit certain education use of copyrighted materials without the usual copyright restrictions.
