Antonio, I follow your advice and try with Harbour 3.4 and now I have this errors: the same: _hb_vmProcessSymbolsEx from adordd.lib and added the follows: _hb_fun_loadlibrary, _hb_fun_freelibrary and _hb_fun_dbskipper, from fiveh.lib I need to upgrade something else, isn't it.? FW9.12, is compatible...
