Thank you Dave
I have run from the FSX folder many times but the files end up in this folder path.
C:\Users\Win 10\AppData\Local\VirtualStore\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X
The files there have the date/time they were created but even if I copy them into the FSX folder the database still cannot be updated.
When running PFE Databse Options, if I select the runways.csv from the VirtualStore path I get this message
"Can't find the FS9 or FSX installation folder!"
If I select the copied files I put into the FSXinstallation folder I get this messge
"Err.75 Path/file access error - ERl: 1100"
Thank you Dave
