I already brought this up in the thread below about PaceNote and HDR, but I am still wondering if and when it is necessary to run RBR or RSRBR as administrator and/or in a Windows compatibilty mode. In the thread below I wrote that after UNchecking Administrator and Compatibilty for RBR I was able to run PaceNote plugin and HDR plugin as well. But meanwhile I have started to install the RSRBR 2015 mod and in the tutorial on rallyesim.fr I am urgently advised to run all the exe's as administrator AND in Windows Vista mode. And from that tutorial I understand that they mean that that is also required when the game is not installed in the default Program Files folder. All my games, including (RS)RBR, are on a separate D partition. Does anyone know an answer ? And if possible not only for (RS)RBR but in general. Thanks in advance.
