Most of the files are .ZIP files which require WinZip to extract.   If you do not have a copy of WinZip, or a version earlier than WinZip 8.0, download and install it now.  Macintosh versions are either StuffIt files (Public Key) or .tar.  Linux versions are all .tar files.

Most Windows applications require the Visual Basic 6 runtime files (marked below with * ).  If you require them (if you have an XP or Vista, you do not need them) in order to run certain Eureka applications you can download them here.   If you still have problems, do a web search for 'vb runtime' and there are many other resources to help you.

None of the applications contain adware or spyware.

See the Products page for information on these applications.
