NCSS 2007 Update (Version 1)
Existing customers who own a license to NCSS 2007 may download and install this file to update to the latest release of the software (Version 1). If NCSS 2007 is 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 has been split from PASS.

If you currently use the NCSS-PASS combined version of NCSS 2007 (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 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 is completely separated from PASS, saving valuable disk space for users not interested in PASS. You are also given the option during the setup process to install GESS (Gene Expression Statistical System for Microarrays). This reduces the space required on your hard drive for installation if you do not need the microarray add-on.

NCSS 2007 Update (Version 0)
Existing customers who own a license to NCSS 2007 may download and install this file to update to the latest release of the software. In this version, NCSS 2007 is combined with PASS 2005. For the most current bug fixes, users must upgrade to Version 1.

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 users upgrade to Version 1 of NCSS 2007 using the link above and then uninstall the NCSS-PASS combined version of NCSS 2007.

NCSS 2007 users who also own PASS 2005 have the following options:

1. Continue to use the NCSS-PASS combined version (Version 0) for both NCSS 2007 and PASS 2005.
2. Run NCSS 2007 using the new version (Version 1) and PASS 2005 using the combined version (Version 0). To get a separated version of PASS, you must upgrade to PASS 2008.

NCSS 2004 and NCSS 2001 Updates
Existing customers owning a license to NCSS 2004 or NCSS 2001 may download and install this file to update to the latest release of the software. This update will install NCSS 2004, but your NCSS 2001 serial number will continue to work. Some new procedures were added in 2004, but with an NCSS 2001 serial number, you will still only be able to use the procedures that were available in NCSS 2001. For upgrade information click here. In this version, NCSS 2004 and PASS 2005 are combined into one physical program.
