So I managed to fix somehow my problem by doing the following.

I started Plan-G using the local pc user and not the network user. Local user has not folder redirection and offline files enabled. So I started Plan-G (note. I did not started by the Plan-G icon on the Desktop, but by running the executable Plan-G3.exe). Plan-G started and created the required data folders on user documents folder (which is a local folder). I made the Plan-G Files folder shared and after the build database process ended I copied the files to the network user's my documents folder and everything worked like a charm.
The only disadvantage is that I have to switch to the local user every time I want to rebuild database, but this is not happening regularly.

Plan-G is great! Thank you Tim!

One feature I would love to see is the ability to see the IVAO traffic the same way I see VATSIM.

I tried the .50 build but same thing happened. I also tried to delete the PlanG3_FSX.sdf file and then rerun PlanG to recreate it and got same error (with some additional .net errors). I did a little research and I found that the SQLCE does not support multiple processes. Since My Documents folder (where the PlanG db is located) is a folder redirection (with offline files enabled), I guess that the "other" process that locks the DB file is the Syncronization process. If I disconnect the network (so I can be in Offline mode) I cannot access the DBs at all, since no DB files are synchronized (Windows feature). I don't want to disable offline folders for my own reasons.

Is there any way that I can "move" the DataDirectory outside the My Documents folders?

Windows 7 64bit

Plan-G v.3.0.0.46

I have installed Plan-G on my computer but I cannot create the database. After processing the sceneries it gets stuck (not hanged, but I have left it the whole weekend and on Monday had not proceeded) on "Writing 103277 Intersections".



I guess the problem is that (as I see on the log)

"There is a file sharing violation. A different process might be using the file. [ \\Lifthrasir\Users\nikolas\My Documents\Plan-G Files\Data\PlanG3_FSX.sdf ]"

My Documents folder is on a network share (through Folder Redirection Group Policy).

Is there any way I can change where the Plan-G Data will be stored?

Thank you in advance
