The HyperChem Web Viewer is a free web browser plug-in that allows dynamic 3D views of molecules. Features include real-time rotation and manipulation, animation of normal modes, picking of spectral peaks and more. The Web Viewer can be used to view the results from HyperChem Professional Release 7.5, HyperChem 7 and HyperChem 6 or any of the molecules in the Hypercube online gallery. The Web Viewer provides an interactive 3D visual experience as opposed to the usual static picture.

NOTE:  The New ActiveX version of the HyperChem Web Viewer now works with Windows XP and Internet Explorer 6.

The technology introduced in HyperChem Release 6 and continued through HyperChem 7.5 for producing HTML files, using "Chemical Objects for the Web" (COW) files, enabling dynamic web display of molecules, orbitals, spectra, etc. was developed using Netscape plug-in technology so that web pages could be viewed with Netscape bowsers as well as Microsoft browsers. Unfortunately, Microsoft decided with Service Pack 2 of Internet Explorer 5.5 and beyond to stop supporting Netscape Plug-ins. Thus, with HyperChem 7.5 of HyperChem this functionality was specifically broken for Internet Explorer 6.0, the current version of the Microsoft browser.

Hypercube, Inc. is making an effort to recover this technology by using ActiveX controls rather than Netscape plug-ins. This release of HyperChem contains a new ActiveX control, IEHin32Control.dll, that replaces much of the previous functionality for Internet Explorer 6.0, i.e NPHin32.dll. The Save As HTML dialog box now allows you to create HTML pages for the new control as well as the older plug-in. Unfortunately, the new ActiveX control does not yet allow display of Spectra but only of molecules, orbitals, and normal modes.

Both the Newer, ActiveX Version and the Older, Plug-in version are available in HyperChem 7.5. The newer ActiveX control works with any version of Internet Explorer, including Internet Explorer 6.0 and later. The older plug-in version works with Netscape 4 and Netscape 6 (Mozilla) and Internet Explorer 5.0, and 5.5, but does not work with Internet Explorer 5.5 SP2 or later.

Note: The Save As HTML feature of HyperChem can only create pages compatible with one version or the other. HTML pages that work in the plug-in version will not work in the ActiveX version or vice versa, even though the COW files are identical.
