[I'm sorry: this (will/may, not sure) only work for those who are registered or have ON1 Perfect Browser v9.5 installed on their computer or if ON1 Perfect Browser is registured to a known email address.]First: here is the link, check it out...
https://www.on1.com/free-upgrade/?v=suiteA night a go I got totally frustrated with how slow ViewNX-i v1.2.9 Windows was running. I may have resolved the problem but I started using ON1 Perfect Browser v9.5 instead. I searched the NET to get help renaming something and never found a solution but...
I read that ON1 is changing it's license program and one can use ON1 Perfect Browser v9.5 but it can NOT be installed now or in the future since the License Number for installing no longer works. To solve the problem ON1 is offering
ON1 Perfect Browser ON1 Photo 10, v10.5.2 FREE.
Now I'm guessing a little but I believe this is free but a major upgrade with cost something like $79.99. So guessing: use this version as long as you like or as long as it works with your OS but pay for the next major upgrade and we want to snag you as a customer for our more expensive products. The download page may be checking for the presence of an older version but I don't think so as I don't remember ever installing ON1 Perfect Browser on a MAC before. I don't think the install program verified an email address but I could be wrong.
I've installed ON1 Perfect Browser on my Windows 7, SP1 and OS X v10.11.6 computers. On the MAC the browser it's call ON1 Photo 10. Anyway here is the link again. Enjoy!
