File/protocol association fails with non-default client data path

[galneon]

Under Windows 7 and 10, .torrent file association and magnet protocol association both fail when launching the client with the -c switch and specifying a non-default data path. Simply nothing happens when opening .torrents and magnet links despite proper association. The only way to add torrents is to save them to a polled directory or add them manually through the "Add Torrent" dialogue. This makes a portable installation impractical, particularly if your one specified polled directory is on the server hosting the daemon which your client PC cannot save files to directly.
