The TMS FireMonkey grid is not a part of the TMS Component Pack for VCL, the FireMonkey grid is part of the TMS Pack for FireMonkey and can be installed separately, there is no order in which to install the TMS Component Pack for VCL and the TMS FireMonkey grid. They should both install correctly and work independently.
As a side note, if you wish to upgrade the grid for FireMonkey to a full pack, you can purchase a license for the full pack on http://www.tmssoftware.com/site/tmsfmxpack.asp and uninstall the XE3 bonus FireMonkey grid.
Kind Regards,
