Sorry to bring this back up, just wanted to add my own recent experience with this. I forgot to deselect enable automatic renewals in FTAM. At some point recently, not exactly sure when, a large number of my licenses were renewed to the latest versions. Logix5000 was renewed to Version 34, and I lost the ability to license all of my old versions on my XP VM. It is still running FTAM 3.62.11, I believe the last version compatible with XP. My Win 10 VM seemed to be fine. After reshosting the Logix5000 license back to v26, I was able to use the license on my XP VM again.
The licenses are all bound to my host, and it has version 32 installed on it. At this point version 10.07 to version 32.00.00 don't seem to have any more problems. I am still working on my View Studio licenses. They were renewed to version 13 from version 12, and I lost that license on my XP VM as well.
