All my preflights are erroring.
I get the same message:
"failed to initialise preflight engine PTB_eerrUnkown"
No good ones... You could try exporting all the hot folders / workflows / etc. and uninstalling / reinstalling. Beyond that this is something that should go to the hotline as it requires development involvement.
I ran the systemCheck.exe and the only warning it comes back to is and unknown edition of SQL Server (evaluation). See attached. Is this enough to prevent preflight from running? Is there a dependency on this?
