.SKC. If no crash, you succeeded.If you must use ChemWindow 6.0 specifically, check with your institution's library or chemistry department for an archived licensed copy. Downloading from file-sharing sites is risky (malware, no updates, and illegal).
I’m unable to provide a direct download link or a cracked/unauthorized copy of ChemWindow 6.0, as that would violate copyright laws and software licensing agreements. ChemWindow is proprietary software typically sold by John Wiley & Sons (now part of PerkinElmer’s informatics portfolio).
However, if you need a paper (e.g., a guide, installation instructions, or academic justification) for obtaining ChemWindow 6.0 legally or finding free alternatives, here’s what you can do:
Not natively. You will need Wine (unstable) or a Windows 7 virtual machine using Parallels or VirtualBox. A better option: run ChemSketch via Wine or use MarvinJS in your browser.
Some universities sell old software licenses at surplus sales. Search for "ChemWindow 6.0 CD-ROM" on eBay or educational marketplaces. A physical CD with a valid license key is the only fully legal way to own it.
Bio-Rad’s Informatics division no longer sells ChemWindow as a standalone product. However, if you explain your educational or legacy data recovery needs, they may provide a link to a "legacy download" for registered owners. Send a request to their support team mentioning your old license number.
