Volume Licensing Service Center – Installing Downloaded Software

Learn how to download and install software obtained from the Volume Licensing Service Center (VLSC), Microsoft's website to help you get installation keys, download or order Microsoft installation software, and access other benefits.



What Software Is Available?

Through the VLSC, nonprofits and charities can download and install any available version or language for your product, as long as the total number of installations does not exceed the number of licenses you obtained through TechSoup. For example, if your TechSoup request included 20 copies of the English version of Windows 8 upgrade product, you could install five copies of this product in English, five copies in Spanish, five copies in French, and five copies of Windows 7 in any language, for a total of 20 installations.

If you see products that you do not recognize in the download list, consult the product use rights (PUR, also called terms of use) for the specific product to understand whether it is available to you. For more information, see the Product Use Rights section of Differences from Retail Products.

  • Office Multi-Language Packs

Organizations and charities that acquire Windows versions of Office products through TechSoup are eligible to request Office Multi-Language Packs through Software Assurance.

  • Service Packs

After a product has been released for a while, Microsoft usually releases service packs or revision updates. Products with these updates included have indications such as SP1, SP2, or R2 in their names. If your computers have the appropriate system requirements, you should usually download the one with the most recent date in the Release Date column.

  • Previous Software Versions

The VLSC offers the current version of its products on the site. You might be able to obtain earlier versions as well.


Before You Start

To download or order installation software, you must either be the administrator or have permission to perform the Download role. For more information, see Maintaining Your Account

Using Downloaded Files

The files downloaded from the VLSC have the file extension .iso. An ISO file is an image of a CD or DVD. An ISO file downloaded from the VLSC is a copy of the installation CD or DVD. You can use the ISO files you download in the following ways.

  • Burning an ISO File to Disc

This allows you to use the burned disc as you would any installation disc. The software will have commands or help topics like: create disc using image; disc copy; burn image. To burn an ISO file to a disc, you'll need software for burning or creating CDs or DVDs.

  • Opening the ISO File and Copying its Contents

You can open an ISO file if you have software that can access the contents of ZIP or CAB files. You can then copy the contents of the image file to your computer.

  • Virtually Mounting the ISO File

You can virtually mount the ISO file if you have software that can virtually mount drives. This allows you to access the ISO file as if it were a disc in a disc drive.
