Microsoft has detailed the system requirements for the new Microsoft Office 2013 suite: However, on March 6, 2013, Microsoft announced that the corresponding distribution rights now apply to retail copies of Office 2013, similar to the Office 2010 commercial license agreements. Transfer of the license from one computer to another belonging to the same user is now allowed every 90 days, except in the event of a hardware failure where the license can be carried over earlier. The first user of the product is now allowed to transfer it to another user.   The second difference, which remains in the updated license agreement, is that the software can only be installed on one computer. In previous versions of Office, this limitation also applied only to OEM editions. Office Retail license agreements allow you to install the product on two or three computers, depending on the edition.  Office 2013 suites and standalone home applications are intended for use on a single PC and do not include cloud services (for example, Exchange Online, SharePoint Online).

Digital copies of Office are also intended to be permanently linked to the hardware on that PC so they can`t be transferred to another computing device. If the buyer wants to use Office 2013 on another computer or if the buyer was unable to later use the computing device on which the original license was downloaded (for example, retail versions of Office 2013 use the Click-to-Run installer). Volume licensing versions use Windows Installer (MSI) technology.  Some editions, such as Professional Plus, are available in both retail (C2R) and volume channel (MSI).
