The installation of the programs listed below that are intended for use under various Microsoft Windows operating systems may not function normally on machines having large capacity hard discs and/or more than 512 MB of RAM. If you experience problems with installation or operation of such programs there may be "work arounds" that will enable their use on your system.

Click here to download the 32 bit Windows version( latest version: 20 June 2009).

For systems that have very large capacity hard drives and more than 512 MB of RAM there is another version of Sunprof (Sunprof6) that may be usable. Sunprof6, however, requires that a user must also install (or have already installed) Microsoft's ".NET Framework 3.5-SP1" software. Users of XP, Vista or Windows 7 probably do have that software already "on board" and will not need to add it. To get Sunprof6 click here. Sunprof has a creation date of 02 March 2010. Before extracting the files from sunprof6.zip please refer to download sm2007.zip
