Installing the Office system
Before you run the Office system setup program, be sure that no other applications are running on your computer.
If you’re installing from the Office Professional Plus 2013 DVD-ROM, insert the disc. On most systems, the Office system setup program starts automatically. If the setup program does not start automatically, click the Run command on the Start menu. In the Run dialog box, type x:\setup.exe (where x is the drive letter of your DVD-ROM drive), and click OK. If you see the User Account Control dialog box and you’re logged on as a non-administrative user, specify the user name and password for an administrative account and click Continue. If you’re logged on as an administrator, click Continue.
