PB15 worked great besides some addon issues, but those were not a huge deal, understandable since its a beta. However, the new update came out, and now it will not let me completely install the update. Says "permissions denied" but installed everthing except for 26mb of uncompressed data. It appears that when I try to give full permissions to X Plane in the preferences, a file in the C172 directory will not allow it. Running Windows 10.
