Hi Alex,
Thanks for your reply. I will look in to this. My ProgramData folder does not have a space, but my Program Files does. I had ignored this because this advisory read as if it was not an issue:
Also FYI ... I am currently running v8.10 and attempting to patch to v8.12. My upgrade from 7.0 to 8.10 in this scenario was successful.
... and if I run a clean install of the environment (no database) and then patch to 8.12 it succeeds.
I will test this to rule it out.
