Thank you for answer, however the problem is still pending. I updated p3d content. I attached problem message.
Then you have a problem with the OTHER DLL/EXE.XML file, not the one you posted, but the one under %APPDATA%
The new location suggested for P3D V3 is %PROGRAMDATA%, and all our installers now use this one but, they will also check the files under %APPDATA%, to be sure you don't have lines from a previous version still there.
So, the corrupted XML files are probably the ones under %APPDATA%. Just to make it more clear: the problem doesn't have anything to do with any of our products, our installers are only indicating a clear error condition caused by other bugged installers (or having edited the file by hand), but they won't dare touching them if they are already corrupted!
