Thank You, This is for third party installers, I am having the issue with the only to aircraft I bought,
FlightFactor and StepToSky team Boeing 757 Professional V2017 and Flight Factor 777 Extended V192. they have updaters which run and these ran when I loaded the aircraft in in X-plane, with both giving the same error. Then I ran them independently and had to associate their updaters with the X-plane installer as they would not run on their own, They ran exactly as the X-plane installer told me it needed an update and then gave the same message in terms of the directory structure, its the "\" which is creating the issue.
I include the log for X-plane from my system. I have now moved the X-plane directory to my Program Files directory and still the same issue. I Initially had the same issue with X-plane then I moved it and the updater is working fine now. I also tried moving their installer to different directories in X-Plane but still it will not complete the update , It finds the data needed to update but will not complete the installation.
Thanks for your help, it is odd that this is doing it for different aircraft.
