Ubaid & Sam, thanks for input.
Some progress, but there seems to be an issue with the IniManager.
Update:
- I uninstalled IniManager (although it was v1.04 - btw updated from v1.03 within the app I think)
- Downloaded and installed v1.04 from Sam's link
- Ran new IniManager (ran in Admin mode, as always), it immediately detected my products, showed two updates available 1) A310 from v1.11 to 1.12 & 2) A300 from v2.01 to 2.07
- The A310 update ran without a problem, updated aircraft
- A300 updated (with full download) to v2.06, then it showed an update available to v2.07. At this stage I shut down IniManager, returned a few hours later, started Manager again and attempted to update. As before, it downloads the update (and this appeared to be a short download) then nothing happens. A300 remains at v2.06, showing update available to v2.07
Note, X-plane was never running during these updates.
Sorry for the long message, trying to help you identify issue.
Hope it helps, Thanks.
