I have checked windows event viewer (aplications) there are no errors.
But this may interest you. I have very old installation file, after installation PF3 discovered old version and started auto update. During this process it updated something but applications was showing the same old version of the software. When tried to update manualy, PF3 gave me information that this is the newest version of the application but I have seen on interface that it is very old version and many new features are missing.
So I started to digging in forums and I have found that sometimes PF3 do not want to autoupdate, so I did it manually via cumulative PF3 update file. Now application shows correct version an all new features are available...but displayer can not connect.
Maybe you have better base installation file, I can reinstal it form new file and try to autoupdate ... maybe it will fix something. maybe this version what I have already it is kind off hybrid
PF3 does not create any folder in main P3D directory, hmm.
