NCSS 2007 and GESS 2006 Update (Version 1)
Existing customers who own a license to NCSS 2007 or GESS 2006 may download and install this file to update to the latest release of the software. If NCSS 2007 and GESS 2006 are already installed on your computer, you may be asked to uninstall the previous version before installing this new version. Select "Yes" to proceed with the update. Your personal files will not be affected. In this version, NCSS 2007 and GESS 2006 have been split from PASS.

If you currently use the NCSS-GESS-PASS combined version (Version 0), this new version will install along-side the combined version. We recommend that you install this version, allow the program to copy your personal settings and data files during the first run of the new version, and then uninstall the previous version.

This new version has two important new features:

1. The Data, Settings, Junk, Macros, and Reports folders have been moved to your "My Documents" folder to make NCSS 2007 and GESS 2006 fully-functional in a limited or standard user environment. These folders all used to be found in the program installation directory (usually \Program Files).
2. In this version, NCSS 2007 and GESS 2006 are completely separated from PASS, saving valuable disk space for users not interested in PASS.

NCSS 2007 and GESS 2006 Update (Version 0)
Existing customers who own a license to NCSS 2007 or GESS 2006 may download and install this file to update to the latest release of the software. In this version, NCSS 2007 and GESS 2006 are combined with PASS 2005.

This version cannot be used in a limited-user environment without giving read-write permission to the Program Files directory. We recommend that NCSS 2007 or GESS 2006 users upgrade to Version 1 using the link above and then uninstall the NCSS-GESS-PASS combined version. For the most current bug fixes, users must upgrade to Version 1.
