With this being a new install, I recommend putting your T:ANE data files, the stuff from your routes, and DLS stuff, in an a location other than the Users/login/App Data/Local/N3V/TANE/Build xxxxx.
I, for example, put mine on my F: drive in F:\TANE_Data. If you only have a single drive, place it in C:\TANE_DATA.
The reason for this is it makes it a lot easier to find stuff if you need to edit content as well as backing up the folder.
Having the data on a second hard drive is the best solution because if you ever need to reinstall the OS, you'll be able to just reinstall the application again and repoint to the existing data folder.
