CUIT recommends that you back up all of your important work prior to any new software downloads. Although unlikely, there is always the possibility of data loss while performing a new installation. When updating to a new operating system, back up all your work and installation files. Remember that you will be overwriting your hard drive with a new operating system.

You have 31 days from the day you check out of the download page to download your software. If you do not wish to install the software at the time you download it, you may archive the download for future installation (for instance, onto a flash drive).

You may want to consider purchasing an Extended Access Guarantee from the download vendor, Kivuto Solutions.  The Extend Access Guarantee ensures that your download(s) and/or key(s) are protected for 24 months.  If you choose not to purchase the Extended Access Guarantee, after 31 days from the day you ordered the product you will no longer have access to your download(s) and/or key(s). If you need to download again, you will be required to pay a retrieval fee to access it again for another 60 days.

For more information, please go to the Help section of the WebStore.

For support, contact Kivuto Services from 6am to 6pm EST (Eastern Time) by phone 1-888-396-1447 or online at

CU Libraries' Applications

Site License Distribution Policies

There are certain policies in place for all licenses procured through CUIT and others that are specific to particular products. The general policies are categorized as follows:

  • The licensee is responsible for his or her own installation and setup. You must not install more copies of the software than you pay for.
  • Any infringement of the license policies becomes the responsibility of the licensee and not Columbia University.

Software will not be prorated, either by price or by duration.

CUIT provides these licenses as a service to the Columbia community. The licensees are responsible for installation, maintaining hardware and making sure the appropriate operating system is installed.

Only the most current versions will be distributed. CUIT does not maintain older, archived versions of software.
