If you installed FlashConnect on Linux in the non-default location and the fcservice won't start, try the following command to reference the actual location of the flashconnect.conf file:

./FCService -C/path/to/file/flashconnect.conf

Where "/path/to/file/" is the actual fully-pathed reference to the directory containing the flashconnect.conf file. Example:

./FCService -C/products/apps/flashconnect/flashconnect.conf
