1. The text mentions the software 'WinScan2PDF' and provides download links for previous versions of the app that are free from viruses and available on Uptodown.

2. It also discusses Apple's iOS 16.6 and 16.7 updates, as well as potential future updates like iOS 16.8.

3. The text lists a few other software applications:

* QuickTextPaste

* TheAeroClock

* DesktopOK

* Q-Dir

These are all Windows-based applications.

4. It provides instructions on how to download previous versions of WinScan2PDF for Windows, including the option to check the app's version history on Uptodown.

As for your original request, 'WinScan2PDF 8.66 for ios download', I couldn't find any information on downloading WinScan2PDF specifically for iOS. The text only mentions previous versions of WinScan2PDF for Windows and doesn't provide direct links to downloads.

If you're looking to download the app for Windows, you can visit Uptodown or other reputable software download websites. However, if you're searching for an equivalent app for iOS, I'd be happy to help you find alternatives that offer similar functionality!
