Quattro Pro Converter is a Windows desktop application. The website CTA is the offline MSI; Microsoft Store remains a real alternate install channel.
If you are visiting from Mac, Linux, iOS, or Android, move to a Windows 10 or 11 computer before downloading the installer.
Both channels install the same app. The website primary CTA is the offline MSI (current trial and version on this site). Microsoft Store is a real secondary alternate and may lag the site trial or version copy. Prefer MSI for air-gapped or scripted installs.
