bulletinstallation/update file for version 2.3.2 dated 10/3/2010 [5.4 MB]
bulletnote: you may have to right-click and select 'Save Target As..." to force your browser to save the file to disk instead of trying to display it. If your security settings prevent downloading the installation executable file, you can try downloading this .zip archive, dcdt+_install_zip.zip instead, which just packages that executable file.
bulletinstallation requires prior installation the Microsoft .NET framework. Which version depends on your operating system (details below). This component is often already present on your computer. If the necessary version of .NET is not already installed, this is detected during installation and it should automatically be downloaded from the Microsoft web site and installed if your computer is connected to the Internet.
bulletFor 32-bit versions of Windows you need to install .NET framework version 2.0, 3.0, or 3.5. If your data analysis computer is not connected to the Internet use this link to download the installation package (dotnetfx.exe, 22.4 MB) for version 2.0 (minimum requirement, okay with Windows 98 thru XP) or this link to download version 3.5SP1 (for Windows XP, Vista, or Windows7: dotnetfx35.exe, ~200 MB) to a flash drive or CD-ROM so it can be transferred and installed onto your computer.
bulletVersions 3.0 and 3.5 of .NET, if already present, are backward-compatible with version 2.0, but version 4.0 is apparently not backward-compatible for 32-bit Windows (or at least the Windows installer doesn't think so). If version 4.0 is already installed on your computer the DCDT+ installer may incorrectly try to download and re-install version 4.0 (this is a Microsoft problem, beyond my control) so you may have to manually download and install .NET version 3.5SP1 and then try again to install DCDT+.
bulletFor 64-bit versions of Windows Vista or Windows 7 the program will install and run with version 4.0 of the .NET framework, which normally is already present. Version 4.0 can be downloaded from this Microsoft web page. Versions 2.0, 3.0, or 3.5 are also compatible (see above for links to download those versions).

SVEDBERG-related files:

Note: the absence of SVEDBERG program updates for several years does not mean program development has halted. This simply reflects the fact that no bugs have been reported since the last update! A major revision is in progress, including a user interface similar to that in DCDT+ version 2.

SEDNTERP-related files:

As of December 2011 SEDNTERP is distributed and supported through the Biomolecular Interaction Technologies Center (BITC) at the University of New Hampshire (the distribution and Help files can be found here.) SEDNTERP version 2 is available for Windows, Macintosh, Linux, etc. The old version, 1.09 (Windows only), can still be found here.

Note: To install SEDNTERP 1 successfully under Windows Vista you must have administrator privileges. After downloading, you may need to right-click on the installation .exe file and use the 'run as administrator' option to start the installation. To run SEDNTERP under 64-bit versions of Vista or Windows 7 you must force Windows to run it in Windows XP compatibility mode.
