Uninstall all the folders that mention TRS19 or N3V and go to your MY TRAINZ page at the top of this page and select the TRS19 download. Make sure you have space on your C drive for the data folder. Any N3V folders on the C drive delete first. Install onto a second HD if you have one. Once installed go to your C drive N3V folder and cut and paste the build folder only to the other drive. Launch Trianz and open settings and select the install tab. Change the destination to where you placed the new build folder. Do a DBR and it should all be in place.
