I wonder if I can change the path of the drive to install RailDriver with 64bit of TS19. If yes, then I have to install RailDriver with 32bit in first then RailDriver with 64bit. Mine is running on D:/ drive not the main drive with C:/. Right now I have the RailDriver with 32bit in C:/ drive and the program of Train Simulator 2019 in D:/.
